COMSWAP.DOC
COMSWAP & COMREST
These companion utilities cure a problem some communications software has
with the PCjr's serial port. When the PCjr internal modem is installed, it
will be recognized as COM port 1, or COM1 and the serial port as COM2. When
the modem is not installed, the serial port is supposed to become COM1. Only
some software cannot find it. To cure the problem, simply type COMSWAP at
the DOS prompt and run your communications program on COM2. This should
avoid any problems. COMREST restores the vectors to their default condition,
something you should rarely need to do.

HUSH.DOC
There is an error, (calling programming errors "bugs" tends to suggest
they are cute little annoyances instead of programming blunders)
a blunder in 3.x which causes floppy drives to have a "grinding" sound
each time the drive is accessed. This problem does not exist in 2.x.
The grinding sound is caused by an incorrect step rate. The speed at
which the disk head is moved is incorrectly set on booting. The
solution is to reset the step rate for floppy drives which can be done
easily if you happen to know what to do. The correct step rate is
already part of DOS 3.x and through the use of the AX register and
Interrupt 13 the correction can be made. All that is needed is to set
the AX register to zero with the instruction "xor ax,ax" and then call
for "int 13." This tiny program needs to end with "int 20" to return
your system to DOS.
xxxx:0100 xor ax,ax
xxxx:0102 int 13
xxxx:0104 int 20
You can create this program with DEBUG or simply use the one that
accompanies this explanation. Insert this tiny COM file in your
AUTOEXEC.BAT file and your floppies, when using 3.x, will purr
like a kitten.

INT9JR.DOC
Like most other jr owners, I was dismayed when I got my update copy of
Microsoft QuickBasic 3.0 and found it typing characters twice while I was
using the built-in editor. I had heard that the jr "would not be supported"
by QB 3.0, but they said the same thing about 2.0, and I use that all the
time. So, I went to see what the trouble was.
The big symptom was the character was being entered on both the make and break
of the keystroke. Ha, bet I caught you with terminology there! The "make" of
a keystroke is simply the key being pressed down, the "break" is when the key
is released. The hardware treats these as two different events, telling the
computer a different thing for the make and break of the same key (the
difference is that the make scan code's high bit is low, while the break's is
high). This to me meant that the break keystroke was losing its high bit
before it got processed by the INT 9H routine, which translates scan codes
into characters. That was also why the shift keys got stuck in the QB3
editor; the computer never saw the break of the shift key, so it assumed you
were always holding it down.
Well, fellow jr lovers, it turns out that the fault in this matter is the
jr's, at least the jr ROM BIOS. Normal INT 9H on a PC and compatible gets the
scan code to process from a "port". When you read this port, it does not
change what is there (it's a "non-destructive read"). Thus, when INT 9H is
grabbed, the grabbing procedure can read from the port and know that it
won't affect anything farther down the INT 9 chain, because they should read
from the port, too, and get the same value. It's a valid assumption, and
MicroSoft assumed it for the QB3 editor's INT 9H grabbing strategy.
But it doesn't hold for the jr. In order to make the jr INT 9 level
compatible with the PC, the jr BIOS uses a three-tiered approach. First, a
software interrupt translates the infrared signals into a 62-key scan code
(this happens to be the NMI interrupt, more on that later). A second software
interrupt then translates this 62-key code into an IBM 83-key code, and then
passes it on to the third software interrupt, INT 9H. This makes the INT 9H
code very similar between the two machines, plus gives the possibility of
adding an 83-key keyboard to the jr. In software, you would just bypass the
first two interrupts and go to the third. (If you don't believe me, look at
the ROM diagnostics with Ctrl-Alt-Ins. There are *two* keyboard diagnostics,
one for 62 keys, the other for 83 keys.)
BUT, even though the second level software interrupt does a write to the port,
the jr INT 9H procedure does NOT do a read from the port. It assumes the scan
code will be coming in the AL register. When INT 9H directly follows the
second level interrupt, that is the case. BUT, if something else has grabbed
INT 9H, it may not put the scan code into the AL register before passing it
on. This is probably why the early version of SideKick, an INT 9H grabber,
didn't work on the jr. In QB3's case, what was in the AL register before it
got to the ROM BIOS to be decoded was the scan code with the high bit masked
off, which explains everything.
The fix is so simple, it's a wonder why Microsoft didn't offer it on the QB
disk package and tell jr owners "Do this to get it to work." All you have to
do is have a TSR program right ahead of BIOS in the INT 9H chain, have it
read the port and put the value in the AL register, and then pass control to
BIOS. When QB3 comes along, it grabs INT 9H from the TSR routine, not BIOS.
When control eventually gets to BIOS, the TSR routine has put things in the
right place.
Well, I wrote it! I call it INT9JR, and I've included the assembly source and
the .COM file with this ARC. Just put it before any other INT 9H grabbing
routine, so it is always followed by BIOS. This typically means putting the
line
INT9JR
as close to the beginning of AUTOEXEC.BAT as possible.
For those of you out there who would rather have a device driver that does the
same thing instead of a TSR, I include INT9SYS. To use it, put the line
DEVICE=INT9SYS.SYS
in your CONFIG.SYS file. You should use either INT9JR or INT9SYS, but not
both (though using both won't hurt).
I've done this, and tried to test it as much as I can. It hasn't interfered
with normal operations, SideKick, comm programs, or editors, and it certainly
makes QB3 work as advertised. But if anybody finds any problems, let me know.
For my next trick .... That NMI thing associated with the jr keystrokes is
the main reason why programs that use the 8087 math chip do not typically work
on jrs equipped with 8087 daughterboards, like TIAC's (the one I have).
Normal PCs have the 8087 use the NMI to signal errors in math, like divide-by-
zero. The program can then grab the NMI to capture such errors without having
to check for them in software, making the program faster. Normally, nothing
else uses NMI, so most programs that grab NMI don't make provisions to pass it
on. So, on the jr, if a program does that, it grabs the interrupt that
enables you to type, basically locking the system if the program wants you to
type something at it. I developed a routine to fix this problem on
Microsoft's mainline languages (C, Fortran, Pascal), and called it JR87OEM.ARC
in the Hardware DL on the CompuServe PC Junior Forum. For QB87, the 8087
version of QB3, that fix isn't applicable, so I'm going to have to come up
with a new one. Trust me, I know what I'm doing.

JRCONFIG.DOC
JRCONFIG Version 2.10
This device driver will make the configuration during the boot
process quick and easy for an IBM PCjr. If you find this program
useful, please send a contribution of $5 or $10 to
Larry Newcomb
9210 Adelaide Dr.
Bethesda, Md. 20817
This contribution will encourage me to continue to enhance this
program, and to write other programs for the PCjr. I have some
other requests for enhancement that are not yet implemented, so I
expect to have another version out in a few months. If you have any
suggestions for future enhancements or other utility programs, send
me a letter and I will consider them.
New to this version:
1 I have changed the names of the two versions to clear up some of
the confusion over which version does what. Also the defaults
for all options now work the same for both versions.
JRCONFIG.DSK - the .DSK signifies a RAM disk and replaces the
old .SYS extension
JRCONFIG.NRD - the .NRD signifies No RAM disk and replaces
the old CONFIGJR.SYS
2 There are some programs that needed to have MODE CO80 run before
they would display boarder colors properly. I believe I have
fixed the -t3 option so this will no longer be necessary.
3 -x option to fix the step rate in DOS 3.1; this will make the
disk drives run quieter.
4 -e option to change the number of entries in the directory of the
RAM disk.
5 -y option to install the jrSynchro cartridge if you have it
plugged in.
6 -p adds a printer online check for shift-print screen, and will
allow selection of lines to print.
7 -h will force the top of DOS user RAM to a given amount.
8 The DEBUG session for RAM.SYS has instructions for changing the
number of entries you can have in the RAM disk directory.
9 The check for the PCjr ROM BIOS has been removed.
You MUST have at least 256K of memory to use this program.
To use this driver put the file JRCONFIG.DSK on a bootable DOS 2.1
disk. On the same disk put the following line as the FIRST line of
your CONFIG.SYS file. Then reboot.
device=jrconfig.dsk
This will:
Install your expansion memory (256K to 640K).
Install a 91K RAM disk in your internal memory (first 128K). This
RAM disk will take the first available letter after your physical
drives (starting with C:). If you only have one drive, drive B:
will still be a phantom drive. By filling up your first 128K, DOS
will be forced to load your programs into your expansion memory,
which will cause your programs to run faster.
Put your screen in 40 column, low intensity, black & white.
Options: ( -c -d -e -h -k -l -p -s -t -v -w -x -y )
-c will turn on the keyboard click.
-d will cause DOS to recognize extra floppy drives, use -dn
option, where n is 1 to 4.
-e will set the number of directory entries allowed on the
RAM disk. The default is 16 entries. Use -en where:
-e1 will allow 32 entries
-e2 will allow 64 entries
-e3 will allow 128 entries
Each entry uses 32 bytes of the RAM reserved for the
RAM disk.
-h is not designed for the average user. I use it for testing
programs I want to put outside the DOS user area. -hnnn will
put nnn as the top of RAM, regardless of how much RAM you
actually have; ie, -h512 will set the top of RAM to 512K. If
you don't have that much RAM, your system will probably
crash. You should NOT use this option and -l at the same
time.
-k will set Caps-Lock (Note: If you have a keyboard with an
indicator light for Caps-Lock, the light will not be turned
on.)
-l will look for extra RAM, starting at 640K and will stop at
736K, and give it to DOS. (Note: 640K is where the ROM stops
testing RAM and 736K is where video RAM "logically" starts.)
This option will only perform a superficial check for RAM.
You will need to use a RAMtest program to check for bad
chips above 640K.
-p will patch the shift-PrtSc interrupt to check and make sure
the printer is ready before it tries to print the screen.
This will stop the system from locking up if the printer is
not ready. If you want to have a form feed (FF)
automatically sent to the printer at the end of the screen
print. Use -pn there n is:
0 - no Form Feed added (default).
1 - the right shift key will add the Form Feed.
2 - the left shift key will add the Form Feed.
3 - either shift key will add the Form Feed.
If you want to be able to select which lines are printed,
use any of the following:
4 or 12 - no FF
5 or 13 - right shift for FF
6 or 14 - left shift for FF
7 or 15 - either shift for FF
With options 4 thru 7 or 12 thru 15:
You can choose which lines on the screen are to be printed.
these lines are put into a buffer until you have added all
the lines you want printed. Then the contents of the buffer
is printed. The RAM for this buffer is the second page of
video RAM, therefore, if you use the -vn option, you must
not use n less than 6. This also means that you can not use
this function if you are running a program that uses
graphics, this function is for alpha modes only.
When you press shift-PrtSc, the cursor will go the top left
corner of the screen.
Use the following numeric keypad keys:
- Use the up and down arrows to move the cursor from one
line to another.
- Use the Insert key to add a line to the buffer. After
moving the cursor to the line you want to print, press
the Insert key. When a line has been selected, that
line is changed to high intensity white on black. This
will not happen on line 25. I leave the bottom line
alone because several programs I use have a status line
on line 25 that is in reverse video, but you can still
print line 25. If you do not want the high intensity on
any line, use n = 12 thru 15.
- Use the End key to print the contents of the buffer.
When printing is complete, the top 24 lines will be put
in low intensity white on black. Again, I leave the
bottom line alone. If you use n = 12 thru 15, the
intensity will not be changed.
- The Delete key will cancel the shift-PrtSc session, and
return to where you were before pressing shift-PrtSc.
- The Home key will cause the normal shift-PrtSc function
to be executed. You should use this if you want to
print a screen from a graphics program.
If you press any other key, you will hear a beep. It is
possible to add a line to the buffer more than once. If the
buffer becomes full, you will hear a beep when you press the
Insert key.
If you press shift-PrtSc while you are already in the
selective print screen mode, the second session will not be
activated (you can only have one shift-PrtSc session active
at a time). However, the shift key you used the second time
will overwrite the one used for the original session. You
can use this feature if you change your mind about whether
or not you want a Form Feed added.
-s sets the size of the RAM disk, use -sn where n is the number
of K bytes you want the RAM disk to be. The RAM disk size may
be a little larger than the value you put in, because of
video page boundaries. The default size is 91K for DOS 2.1
and 79K for DOS 3.1. (10K is the smallest RAM disk you can
have, because that is how much room is left on the video
page where IBMDOS.COM is loaded with DOS 2.1, and this space
can not be used for anything else anyway. With DOS 3.1 you
get about 15K, because IBMDOS.COM is larger and video RAM
must be moved to a higher video page). There is no upper
limit on the size of the RAM disk (other than the amount of
RAM you have in your computer).
-t will set the video display mode, use -tn where n is:
Alpha Modes
0 for 40 X 25 B/W (Default)
1 for 40 X 25 Color
2 for 80 X 25 B/W
3 for 80 X 25 Color
Graphics Modes You can get some funny looking
4 for 320 X 200 4 Color screens when you boot up in a
5 for 320 X 200 B/W 4 Shades graphics mode because DOS expects
6 for 640 X 200 B/W 2 Shades to be in Alpha mode.
7 is not a valid mode
Extended Graphics Modes
8 for 160 X 200 16 Color
9 for 320 X 200 16 Color
10 for 640 X 200 4 Color
-v will reserve video RAM, where n is 4 to 96. Normally 16K is
set aside for video RAM, you can either decrease or increase
this amount with this option. Using -v4 will reserve 4K for
video, giving you an extra 12K of user RAM, but you must not
use any graphics modes. If you are concerned about speed,
you may not want to use this option with a value less than
16. The extra RAM that you get this way will be in the video
page, and that will be in the first 128K. Any other device
drivers and COMMAND.COM will load into this area. Unless you
have some large device drivers, the regular DOS programs you
run will start in this low RAM. Don't be fooled by the size
of the files on the disk. JRCONFIG is over half
initialization code, the resident portion is less than 1K.
Only about 3K of COMMAND.COM will load into low memory, the
rest is the transient portion that is at the top of DOS
memory. High values are used for reserving RAM to be used
for high-res graphics (32K) or extra video pages.
-w will put a clockwise spinning character in on the top row of
your screen, use -wnn where nn is the column you want it to
appear in.
-x will set the proper step motor rate in DOS 3.1, this will
make the disk quieter. Note: this will not take effect until
after you see the initialization message.
-y will install the jrSynchro cartridge if you have it in a
slot. If you are not familiar with this cartridge. It
replaces the keyboard and floppy disk interrupts, and allows
the keyboard to be used while the disk drive is being
accessed. It seems to work fine with DOS 2.1, but there are
some problems with DOS 3.1.
It also will give you a 47 character buffer (DOS gives you
15 characters) if you install the buffer in the first 64K of
RAM. Unfortunately, this is very restrictive if you want to
force your programs into expansion RAM. This is the primary
reason I install it in JRCONFIG. I allocate the buffer
inside JRCONFIG, which is always in the first 64K. If you
want the 47K buffer, you can put JRSYNC47 in your
AUTOEXEC.BAT. I have used two versions of the cartridge, 1.2
and 1.4.
Use:
-y for version 1.2
-y1 for version 1.4 with parity check
-y2 for version 1.4 with no parity check
If you have another version, try using one of the available
options anyway. If you see JRSYNC in the initialization
message that JRCONFIG prints, then JRCONFIG found the
cartridge. If your computer locks up, you have an
incompatible version.
Cartridge Basic compatibility:
Cartridge Basic is written to run in the low RAM of an unexpanded
PCjr. If you have a copy of JBASIC.COM, you can run it to enter
Cartridge Basic when using expansion RAM. It is a short program
that sets up an environment for Cartridge Basic to run in. One of
the things it does, is it gets information from the RAM disk
device driver about low memory and the video page. JRCONFIG will
give it the information it needs to set up the proper
environment. It also checks for a hardware register that is on a
MS Booster. If it can not find this register, it will abort.
Below is a print out of a DEBUG session that will remove the
check for the MS Booster, and change the drive that it expects
the RAM disk to be. If JRCONFIG is drive C:, you can ignore the 2
lines that change the drive from C: to D:. If JRCONFIG is E: then
change the 03 to 05. The fourth to last line changes the name that
DEBUG uses to DBASIC.COM, so that DEBUG will write a new file. I
chose the name DBASIC.COM because this new modified program will
work when JRCONFIG is D:. The 6797 at the beginning of most lines
will probably be a different number for your DEBUG session.

JRCONFIG.NRD (formerly called CONFIGJR.SYS) is the version
that will not install a RAM disk. This version will not cause
problems with hard disk drivers that insist on being drive
C:. All the defaults are the same as they are in
JRCONFIG.DSK. If you want your hard disk device driver to
load into external memory, do not use the -s option. This
will waste some of your internal RAM, but your hard disk
driver will run faster. If you have one of the hard disks
that have a ROM on the controller, you may still experience
some increase in speed by sacrificing your internal memory,
because all device drivers and COMMAND.COM will load into
external memory. You should experiment to see if it makes a
difference for your configuration. One of the enhancements
that someone has requested is a way to use the low RAM that
is wasted by not using the -s option. I will probably
provide this with the next release.
EXAMPLE:
device=jrconfig.dsk -d2 -t3 -c -p6
will:
Tell DOS you have two floppy disk drives.
Boot up in 80 column color mode.
Turn on the keyboard click.
Cause the shift-PrtSc key combination to first check for the
printer to be ready, then allow selective print screen, and
add a formfeed if the left shift key is used.
FOR BEGINNERS:
Here is a quick and easy way to start using this program. Format a
new disk using the /s paRAMeter. This makes the new disk a bootable
disk. Refer to the DOS manual if you have not used the FORMAT
command. Then copy JRCONFIG.DSK to the new disk. Then type the
following three lines from the DOS prompt:
copy con config.sys
device=jrconfig.dsk -t3 -c
^Z
The first line tells DOS to copy from the keyboard to a file called
CONFIG.SYS. The second line is what is put into the file, you can
add any other options to this line you want. The third line is the
end of file marker, DOS will add this to the file if you press the
F6 function key.
I hope this is as useful to others as it has been to me. If anyone
has any questions about this device driver, or if you think there
is a bug, you can write me at the address at the beginning of this
documentation, or you can leave me a message on Battleship
Pennsylvania 301-428-3145. This bulletin board is associated with
the METRO PCjr USER GROUP.
I have included another program that I find useful. I get very
annoyed at the DOS message to insert a disk with COMMAND.COM and
press a key. I think that putting COMMAND.COM on all my disks a
poor answer. I got this program from a bulletin board, and it has
made my life much easier.
COMSPEC.COM - If you put the following 3 lines in your
AUTOEXEC.BAT, you will always have COMMAND.COM on your RAM disk that
is created with JRCONFIG.DSK.
1. set comspec=c:\command.com - this line uses the DOS 'set'
command to tell DOS where to find
COMMAND.COM; however, there is a
bug in DOS and this doesn't work by
itself.
2. comspec c:\command.com - this line executes the program
COMSPEC.COM, which causes DOS to
recognize the 'set' command
3. copy command.com c: - this line copies COMMAND.COM to
the RAM disk
NOTE: The numbers at the beginning of the 3 lines do not go in
AUTOEXEC.BAT they are only there for easier reading.If you have 3
or 4 floppy drives, then the RAM disk will be D: or E:
I modified RAM.SYS to have a spinning character in the upper right
corner of the screen. It is 2 spaces to the right of the one for
JRCONFIG.DSK and spins counter clockwise. For those of you who
don't already have it, add the following line to your CONFIG.SYS
device=RAM.sys
This will install the device driver. You then run the program
SETRAM.EXE.
setRAM d n
Where d is the drive specifier and n is the number of K bytes to
use for the RAM disk. The RAM disk will take the next available
letter; therefore, if you have three floppy drives (A: B: C:),
JRCONFIG.DSK will be drive D:, and RAM.SYS will be E:. You may want
to add this line to your AUTOEXEC.BAT. You can have RAM.SYS
installed more than once in CONFIG.SYS, each occurrence will take
the next drive letter.
You can remove the RAM disk at any time by running
setRAM d
This will free up the RAM used by the RAM disk. NOTE: you will loose
any files that were on it. You can then recreate the RAM disk at any
time, because the device driver is still installed.
If you want to move the spinning character to the left, you can
change the position using DEBUG.COM. You can also change the number
of directory entries. The following is what a DEBUG session will
look like. The hyphens are the DEBUG prompt and are not typed in.
debug RAM.sys This starts the program.
-e284 If you want to move the spinning character.
XXXX:0284 9E.nn DEBUG responds with everything on this line
except the nn. This will be the new offset
of the spinning character. Subtract two from
hexadecimal 9E to move one space to the left;
ie, nn can be any even number from 0 to 9E.
-e126 If you want to change the number of directory
entries
XXXX:0126 40.nn Replace 40 (64 decimal) with nn, the number
of entries you want. I suggest you only use
even multiples of 10 (16 decimal). 80 (128
decimal) is probably as high as you will want
to use. Every 10 (16 decimal) entries will
use 512 bytes of memory.
-w This will cause the modified program to be
written to the disk.
Writing 01B9 bytes The message from DEBUG.
-q Ends the debug session.
JRSPOOL.DOC
PRINT SPOOLER FOR JUNIOR
This program will install in your ram a print spooler which
will allow junior to use part of its memory to collect
data and hold it for the printer. There by releasing the
computer (CPU) back to you while it contiues to print !!
To set it: When the A> prompt appears, type JRSPOOL and two
numbers (with a space in between). The first number indicates
whether your parallel printer is LPT 1: or LPT 2:. So enter
a 1 or 2. The second number indicates how many 4K blocks of
memory you want to set aside for spooling (printing while
working).
Hint: One page of printed text is nearly equal to one 4K
block.
Example: If you want to reserve 8K of memory for a spooler
for LPT1:, type: A>JRSPOOL 1 2 (Press Enter).

Machine Configuration
JRTELE.COM will run on 128k PCjr with an external
speaker, a color or monochrome 80-column display, an
internal IBM or external Hayes-compatible modem (at
300 or 1200 bps), and a single disk drive. It will
also support a RAM disk if you have the additional
memory.
Other configurations (second disk drives, etc.)
may or may not work. This program depends heavily on
PCjr specific interrupts and ports. If it doesn't
work on your specific configuration, register and
advise the author of the problem. If it can be fixed
without changing the basic purpose of the program, it
will be incorporated into a future release. There are
no plans, currently, to make JRTELE.COM work on a PC,
XT, AT, or other "compatible".
IMPORTANT NOTICE
If you are using add-on memory and are changing
the location of the screen memory, you must allocate
enough memory for two (2) pages of screen memory. If
this is not done, results are unpredictable.
Machine Configuration
JRTELE.COM (Rel. 1.0) 3
Introduction
JRTELE.COM is a communications program written
specifically for the PCjr. It makes full use of the
Video Gate Adapter, the internal sound chip, and an
IBM internal or external Hayes compatible modem, and
optionally a printer. It also supports a capture
buffer (to a maximum of 32k). It is designed to
communicate with RBBS, using its color graphics and
music, FIDO type, and NOCHANGE bulletin board systems
(BBS). NOCHANGE graphics, music, and NMODEM protocol
are not currently supported. This is the basic
purpose of this program and it will not be altered in
future releases.
JRTELE.COM was written in Turbo Pascal V3.01A
with the BCD option. There are approximately 4000
lines of source code in the program. The source code
is available with a limited use license; see the user
registration information at the end of the manual.
The communications routines in JRTELE.COM are
based on the program DUMTRM.PAS by Jim McCarthy of
Borland International and Andy Botany of Teleware
Incorporated. The disk directory read routine is
based on the program QDL.PAS also by Jim McCarthy of
Borland International. Both programs are in the
public domain and are available on the Borland
International SIG on Compuserve and some BBS's.
The following limitations are present in this
version of JRTELE.COM:
1. Only odd, even, and no parity are supported.
2. Only 300 and 1200 bps are supported.
These limitations do not prevent JRTELE.COM from
performing its purpose as stated above.
If you are using an IBM internal modem, it has
had a revision since its first release. The later
revisions (marked "REV J" and later) corrected a
problem occuring during transmission of non-text
files; i.e., uploads of programs would not work
Introduction
JRTELE.COM (Rel. 1.0) 4
properly. If you own an internal modem with a
revision identification lower than "J", you may have
problems with XMODEM uploads. Unfortunately, this is
a problem beyond the control of JRTELE.COM or its
author. If possible, upgrade to a revision "J" or
higher of the IBM internal modem.
If you are using a Hayes compatible external
modem, it must be truly compatible in the command set
and responses. If it is a Hayes compatible and does
not work properly with JRTELE.COM, it's probably not
as compatible as you think. (Paraphased from Borland
International.)
Introduction
JRTELE.COM (Rel. 1.0) 5
Getting Started
Be sure and read the important notice in the
machine configuration chapter if you have more than
128k of memory. Also make sure the volume on your
external speaker is high enough to hear the sounds
generated by JRTELE.COM.
To begin, type (without the quotes) "JRTELE.COM"
at the DOS prompt (a:>, where a is the default drive
number). The first time you run JRTELE.COM, it may
ask you for information which then becomes defaults
for the program and the dialing directory. The
control file is then written for future runs. The
directory file is created, using the defaults, for
later runs. The next time you run JRTELE.COM, it will
read and use these files. If you are using an IBM
internal modem, the defaults are set to 300 BPS, 8
data bits, 1 stop bit, and no parity. If you are
using an external modem, you are asked for its speed.
Then the defaults are set using the speed you
supplied, 8 data bits, 1 stop bit, and no parity.
These are the communications parameters recommended by
most BBS's. Later in the documentation, instructions
are given on changing the defaults.
If you are using the IBM internal modem, it is
not necessary to enter any commands to set the modem's
format, dial a number, or do uploads. JRTELE.COM was
written to do that for you.
A few comments about the notations used in this
documentation and the program. When the phrase "Alt-"
proceeds a letter, it means you should hold down the
key marked "Alt" key (to the left of the space bar)
while pressing the named letter key. It is not
necessary to also press the shift key, even if the
indicated letter is capitalized. For example, Alt-M
means: hold down the "Alt" key while pressing the "M"
key. The phrase "Ctrl-" preceeding a letter means to
hold down the "Ctrl" key (to the left of the "A" key)
while pressing the named letter key. Again, it is not
Getting Started
JRTELE.COM (Rel. 1.0) 6
necessary to press the shift key. The phrase "Fn-"
and number or phrase implies you to press the "Fn" key
(top right corner of the keyboard) and the number or
phrase key. Additional information about key
combinations can be found in the IBM manual, Guide to
Operations, supplied with your PCjr.
When you see angle brackets around a letter in a
word, it means you use that letter to select the
action implied by the word. For example, the word
"e<X>it" means you are to press the "X" key to exit
from the routine. Again, it is not necessary to press
the shift key with the letter.
On occasion, JRTELE.COM will request a name,
phone number, or other information from you. When you
provide this information, certain keys can be used to
change what you have entered before you press the
Enter key. The backspace key will backspace one
character position and put a space there. The Esc key
will backspace over all characters you have entered.
The Enter key indicates you are finished entering
characters.
JRTELE.COM will inform you (visually and audibly)
that it is ready. It will also tell you how large the
capture buffer is; usually, it will have between 12k
(on a 128k PCjr) to a maximum of 32k (on PCjr's with
extended memory). When you've read the first screen,
you can press any key to continue. If this is your
first time running JRTELE.COM, press Alt-M to display
the menu.
Getting Started
JRTELE.COM (Rel. 1.0) 7
Menu
The menu screen is provided to give you a quick
summary of the functions available. Each of these
functions is listed below along with a brief
description of that function.
Pressing any key will take you out of the menu.
If it is a function on the menu, that function will be
performed. Most functions perform in this manner.
The function window will remain on the screen until
you press a key; the key you press will be sent or
the appropriate function will be performed, based on
the key. The exceptions to this are the dialing
functions (Alt-D and Alt-Q) and the file transfer
functions (Alt-R and Alt-T). Remember, the shift key
is not required for "Ctrl-" and "Alt-" combinations.
Alt-P Communications Parameters
Allows you to set the communications parameters.
This is used primarily when making a manual
(i.e., not in the directory) call.
Alt-F Program Defaults
Allows you to set the parameters used by the
program; e.g., screen colors.
Alt-E Keyboard Echo
Allows you to see the characters you enter if the
system with which you're communicating (host)
doesn't echo (send back) the characters you type.
Most systems do echo.
Alt-C Clear Screen
Clears the screen.
Alt-X Exit Program
Allows you to exit the program after answering a
verification question.
Menu
JRTELE.COM (Rel. 1.0) 8
Alt-M Show Menu
Shows the menu screen.
Fn-Echo Echo to Printer
Allows every character received and typed to be
sent to the printer. Obviously, you must have a
printer attached and it must be ready. Toggling
the printer on and using 1200 BPS may cause loss
of characters sent by the host.
Fn-PrtSc Print Screen
Allows you to print the screen, including any
window visible. The normal print screen function
is changed while JRTELE.COM is running. This
allows the program to tell the sender to stop
sending while the screen prints; this helps
prevent the loss of characters from the host.
When printing is completed, the sender is told to
resume sending.
Alt-D Dialing Directory
Brings up the dialing directory. You may add,
change, and delete entries; call an existing
entry; make a manual call; redial the last
call; and, of course, do nothing. Dialing may be
terminated by pressing any key. A later chapter
details this function.
Alt-Q Redial Last Number
Redials, repeatedly, the last number dialed.
This can be terminated by pressing any key.
Alt-Z Show Elapsed Time
Shows the time since the last call was dialed;
useful when you're using long distance.
Alt-H Hangup modem
Forces the modem on-hook (i.e., it hangs up).
F1 - F10
Sends the value associated with the pressed
function key from the associated directory entry.
Not effective with manual calls.
Menu
JRTELE.COM (Rel. 1.0) 9
Alt-B Send Break
Sends a sustained break signal. May be required
by some systems, but not most BBS's.
Alt-L Logged Drive
Shows the current logged drive and allows you to
change it.
Alt-V View Disk Directory
Displays an abbreviated directory and free space
on the current logged drive.
Alt-R Receive File
Sets the program in file receive mode. A later
chapter discusses file transfers.
Alt-T Send File
Sets the program in file send mode. A following
chapter discusses file transfers.
Alt-Y Delete File
Allows you to delete a file.
Alt-O Open Buffer
Opens the capture buffer; that is, starts
capturing each character sent and received.
If the buffer was previously open, the capture
starts without destroying the buffer contents.
Alt-K Clear Buffer
Clears the capture buffer. Once cleared, the
data is lost.
Alt-W Write Buffer
Writes the contents of the capture buffer to a
file you've specified as the log file for the
current call. After writing, the buffer is
cleared.
Alt-I Close Buffer
Closes the capture buffer; that is, stops
capturing data. No data is lost or written.
Menu
JRTELE.COM (Rel. 1.0) 10
Dialing Directory
The dialing directory is used to store the name,
dialing prefix (for example, long distance service
phone number and access code) indicator, phone number,
communication parameters, echo required, line feed
needed, XOn/XOff protocol codes, last connected time
and date, log file specification, and function key
values.
In order to maintain a directory as large as
JRTELE.COM's directory, frequent access to the
directory file must be made. If you remove the disk
containing the directory, you must replace it prior to
disconnecting a call or entering the dialing directory
function. The directory file is always closed except
when it is being accessed; that is, the file will be
opened, used, and closed as necessary.
Pressing Alt-D takes you into the dialing
directory. Once there, you can dial a number by
entering the number to the left of the name of the BBS
you are calling and pressing Enter. The name and
phone number being called will be displayed at the
bottom of the window. If a connection is made, you
will be notified visually and audibly. If no
connection is made, a message will be displayed and
the program will pause before redisplaying the
directory.
Calls may be placed to numbers not in the dialing
directory by entering a M (for manual call) and
pressing Enter. The program will ask you for a prefix
code ("!" or "@" as stored in the program defaults and
used to access long distance services) and then the
phone number. After they are entered, the program
will proceed as if the call had been made from the
dialing directory; however, there are no values
associated with the function keys.
The last dialed number (from the directory or a
manual call) may redialed by entering an R and
Dialing Directory
JRTELE.COM (Rel. 1.0) 11
pressing Enter. The program acts as if you had exited
the dialing directory and pressed Alt-Q.
Entries may be changed or added by entering a C
and pressing Enter. You will then be asked the number
of the entry to be changed; enter it and press Enter.
The current values for that entry will then be shown
and you change may them individually. Enter the
letter of the appropriate value and then the new
value. After all changes have been entered, press the
"Esc" key. Remember, the prefix in the dialing
directory is a "!" or a "@" which relate to long
distance service access prefix definitions in the
program defaults, not modem dialing prefixes. Phone
numbers may contain 14 characters; valid characters
are the digits 0 to 9 and other characters supported
by your modem. Consult the documentation supplied
with your modem. Normal usage (that is, without a
switchboard) requires only that you enter the phone
number of the BBS as you would dial it yourself. If
you use a long-distance service, you should store the
phone number and access code for the service in the
program defaults and the phone number of the BBS in
the directory. Tone and pulse dialing requirements
are also maintained in the program defaults.
Entries may be deleted by entering a D and
pressing Enter. You will be asked which entry to
delete; enter the number of the entry and press
Enter. The entry will be reset to the initial program
defaults.
To view additional entries, use the Home, End,
PgDn, and PgUp keys (lower right corner of the
keyboard); remember these keys require you to press
the "Fn" key first. Home will display the first 15
entries in the directory. PgUp will display the next
15 entries. PgDn will display the previous 15
entries. End will display the last 15 entries in the
directory.
To exit the dialing directory, enter an X and
press Enter. You will be returned to the main screen.
Dialing Directory
JRTELE.COM (Rel. 1.0) 12
Important Notes
If you captured data during a call and you enter
the dialing directory with data in the buffer, the
program will ask you what to do with the data in the
capture buffer. You may clear the buffer, write it to
a file of your choice, or write it to the log file for
the last call made. If the file you specify exists,
the data will be appended to that file. If you select
to write the file, but have not specified a file name,
a file name of "DEFAULT.FIL" is used.
When sending the values corresponding to the
function keys (F1 through F10), JRTELE.COM will always
add a carriage return. To prevent this, enter a
backslash (\) as the last character of a message. The
function key values are useful for storing your first
and last names, your password, and other frequently
entered strings associated with that entry in the
directory. For example, F1 could contain your first
name, F2 your last name, and F3 your password. This
can save several keystrokes.
Another good idea (made easier by the function
key values) is to use a unique password on every BBS
you call. If a computerized vandal (also called
"hacker", "cracker", or "wrecker") manages to break
into a BBS and get a list of users and associated
passwords, that vandal won't be able to get onto other
BBS's with your name and password and then wreak their
perverse, infantile havoc while destroying your good
name and probably your ability to use the wrecked
BBS's. Unfortunately, it's happened before and will
continue.

Communication Parameters
These parameters are used to set or reset the
communications parameters used for manual calls (the
dialing directory maintains the parameters for calls
made from the directory). The most common parameters
are listed for easy selection and entry. If these do
not meet your needs, select option 6 to specify the
required settings. If you are using the IBM internal
modem, the settings you select are checked for
validity.
Once selected, the parameters are changed for
both the serial port and the modem. The parameters
are changed in a manner and sequence appropriate for
the modem you are using.
Communication Parameters
JRTELE.COM (Rel. 1.0) 14
File Transfers
JRTELE.COM supports ASCII (XON/XOFF) and XMODEM
protocol transmitting (uploading) and receiving
(downloading) of files. There is a wealth of public
domain programs (an astounding number of which run
with no problems on the PCjr) available on the BBS's.
If at all possible, it is recommended you use the
XMODEM protocol to transmit or receive files, even
text files. XMODEM has a 99.5% accuracy rate; your
chance of receiving an error during the transfer is
slim. ASCII transfers do no error checking; your
exposure to error is then dependent on the telephone
line, the weather, and any number of other
uncontrollable items.
To receive a file, enter Alt-R. To transmit a
file, enter Alt-T. Once in file transfer mode, you
will be asked to specify a file transfer method;
press the appropriate key. Then you will be asked for
a file specification; enter a normal file
specification (drive:name.ext). The methods supplied
for receiving files are XMODEM and ASCII. For
transmitting files, you may use XMODEM, ASCII, and
Paced ASCII. Paced ASCII is useful if you compose
messages offline (not connected to a BBS, using a
text/word processor), then enter them into the BBS
mail section. Most BBS's use a colon (:) after a line
number for pacing. Check your BBS carefully before
you do this; there are no real standards of line
length or number of lines.
As an alternative to using Alt-R to download text
files, open the capture buffer then tell the host to
ASCII download the file. If the file is larger than
the buffer, the buffer capture routine will tell the
host to stop sending and tell you the buffer is full.
You may then write or clear the buffer. The clear
buffer routine will tell the host to start sending
again. Remember, the write buffer routine also clears
the buffer after writing it.
File Transfers
JRTELE.COM (Rel. 1.0) 15
Another note about ASCII downloads: the data
being received is not displayed. Since some files do
not have an end-of-file character, the receive file
routine will not know it has received the end of the
file. Watch the number of characters received and the
length of the file; that way you will know when to
stop the receipt of the file.
The program uses the capture buffer to store data
during file transfers; therefore, the capture buffer
will be written before sending or receiving a file.
Also, the buffer is filled before anything is written
to disk, so don't panic if the disk doesn't spin much.
It was designed that way.

JRTELE.COM (Rel. 1.0) 16
Program Defaults
The program's defaults are available for change.
These include the text color, background (and border)
color, the window text color, window background color,
default BPS rate, default stop bits, default data
bits, modem type, redial delay, and tone with program
messages. (Note that all "BEEP"'s issued by the
program cannot be turned off; certain critical
messages will always cause a "BEEP".) The access
numbers for long distance services are also maintained
in the program defaults as prefix codes "!" and "@".
Pressing Alt-F will get you into the default
change routine. The defaults are listed, then you are
able to change them individually. Just enter the
letter of the default to be changed, then the
appropriate value. To indicate you have no more
changes, press the Esc key. You will then be given an
opportunity to save the changes for future runs.
Any changes made to the program defaults will be
effective immediately after you exit the default
change function, whether the changes were saved or
not.

Error Messages
Error messages are displayed at the time of the
error. Usually, JRTELE.COM will display the error
message, then continue as if the request causing the
error was not issued. When you are requested to
select from a set of values, if you do not choose from
the indicated values, JRTELE.COM will just ignore your
selection.
The only coded (non English) error messages you
should get are listed below with their cause.
Error Meaning and action

PATCH.DOC
DOS PATCH UTILITY Version 1.20
PATCH.COM is a utility intended to make disk based patches to DOS files. PATCH
patches the files at an absolute offset in the file, or is capable of adding to
the end of the file. The maximum size the file to be patched can be is 64K
Syntax for the command is as follows:
PATCH [d:][path]filename.ext [d:][path]
where the first string is the name of the file containing the patches and the
second string is a path pointing to a directory containing the files to be
patched. For example:
PATCH C:\PATCHES\DOS20 A:\
would look in the \PATCHES subdirectory for the file DOS20. This file should
contain the patches. PATCH would then look for the files to be patched in the
root directory of the A: drive.
PATCH will default to the current drive and current directory if a path and a
drive letter are not specified. For example, for a user to install a patch to a
DOS disk, the easiest way to install the patches would be to copy PATCH and the
file containing the patches into the directory containing the files to be
patched. Then by making this directory the current directory on the current
drive, the patch could be made by simply going PATCH filename.ext. For example,
using the patch file DOS20 the intall procedure would be:
PATCH DOS20
This would patch files in the current directory of the current drive. By using
the defaults, it becomes much simplier. As typically the DOS files will be in
the root directory of a diskette, installing the patches should be an easy
process. Note that PATCH does not work on write protected diskettes. If a user
wishes to patch DOS files, he should make a non write protected copy and then
patch the copy.
To distribute PATCH, a user should be given a copy of PATCH.COM, the appropriate
patch file, and a list of what files are patched and the problems fixed.

PATCHBAS.DOC
NOTE: THIS ROUTINE WORKS BEST WITH THE VERSION OF BASICA.COM THAT COMES WITH
PC-DOS 2.1. UNPREDICTABLE RESULTS MAY OCCUR WHEN IT IS USED WITH LATER
VERSIONS OF BASICA. THIS SHOULD NOT BE A PROBLEM FOR MOST PCjr USERS SINCE
MOST HAVE DOS 2.1.
There was a file called BASICAJR.DOC on the California junior BBS at
1(213)659-7187 that explained how to use Debug to patch BASICA.COM so that it
would run on an IBMPCjr without cartridge basic installed. Usually when you
try to run any version of basic on a jr., you must have cartridge basic
installed. If you don't, you will get a message "Cartridge Required" as
explained on p. A-7 of jr's Basic manual. With this patch, you do not need to
have the basic cartridge inserted; all you need is the patched version of
BASICA on disk.
There are two reasons why running BASICA from disk is a good idea.
First, it lets you use basic even without the special junior cartridge
version, which you might want to do because you haven't got it or because
you have other special purpose cartridges in both slots and want to run a
quick basic program without rebooting the machine.
Second, because of the way cartridge basic checks for whether there is
enough memory on the machine to run basic, if you have over 256K on your junior
you may get an "Out of Memory" statement and won't be able to run basic even if
you know you have 640K. This is because cartridge basic does an Int 12H to get
the total amount of memory, but it only reads the "low byte" returned. This
means that with more than 256K, it may think that it only has 18962 bytes free,
not enough. Disk basic will still run fine in this case. The solution that
most makers of hardware like memory expansions or second drives for the junior
suggest, is to keep a copy of unmodified DOS to run basic with, but that is
very inconvenient. It means, for instance, that you can't run a quick basic
program to set up your printer or keep a log of computer usage when running 123
or a full-size word processor. This patched version will work in those
circumstances.
There are two small problems with this patch.
First, the original patch disabled the "soft" keys, the function keys
that show up on line 25 of the basic screen. (See jr's Basic manual, p. 4-158.)
You would have to type in "RUN" instead of using Fn2. I have written a short
basic program that corrects this; if you run it whenever you start disk basic,
the function keys will work. You might want to modify the function keys after
you take a look at this program and pp. 4-157 to 4-159 in the junior basic
manual; you can set up a function key to clear the screen and return to the
system if you like, or anything else you want. While you are at it, you can
change line 0 of the program to use colors you like; I have just added line 0
because I like those colors on my basic screen. You don't need to do any of
this if you don't mind the lack of soft keys. If you do want to use the soft
keys, to start basic with soft keys enabled type BASICAJR KEY then hit return
key.
Second, cartridge basic has several features and commands that disk
basic doesn't. If a program was designed specifically for cartridge basic on
the jr, it may not run under BASICA. Except for those programs written
specifically for jr's cartridge basic, disk basic should be o.k..
The simplest way to get disk basic is to just rename a copy of
BASICA.COM something like JRBASIC.COM. This works fine if you always keep
your basic cartridge in one of the slots, but if you have two other cartridges
there and try it, you will get the "Cartridge required" message. This patched
version of BASICA must also be renamed; if you just type in BASIC or BASICA,
you will get thrown into the cartridge version. The automatic patch will rename
BASICA BASICAJR.COM (for BASICA jr version). To run disk basic, always
remember to type in BASICAJR; to run it with working function keys, type in
BASICAJR KEY.
To patch your copy of BASICA.COM, you must have copies of the following
files on your disk:
BASICA.COM (program to be patched)
DEBUG.COM (program that does the patching)
PATCHBAS.BAT (program that automates the process)
PATCH.TXT (file that tells debug what to do to basica)
At the DOS prompt, type in PATCHJR; everything else should happen
automatically. When you see the DOS prompt again, you should have a patched
version of disk basic.
