Subject: Com3 Kermit
I had not received the Kermit Info-Digest V6N13 when I sent my note
to the IBM PC Info-Digest regarding my hacked copy of MS-Kermit 2.29
that supported Com3. Even though it took over a week for the files
MSR29C.UPD and MST*.BOO (MSTIBM.BOO in particular) to show up on
KERMSRV at UOFT02 after they did on KERMSRV at CU20B, I have them now
and recommend them over my version.
Joe did not wait for me to update my modifications (I don't blame him;
I was taking too long) for version 2.3 so com3 & com4 support are in
MS-DOS Kermit 2.29C. Since my version is obsolete I will not be sending
it to those who have requested it from me. If you really need the old
version of kermit with COM3 support, send me another request and I'll
send a BOO file of the binary. I do not plan to distribute the source
because it is both large (about 1 MB), obsolete, and contrary to C.U.'s
policy of distributing source to minor releases.

Subject: Gemini Printer Problem
Regarding using a Gemini printer in graphics mode as an Epson-compatible
printer:
The problem the Gemini printer has is that the linefeed jump is not the same
as it is for an Epson; there is an 8/144 inch discrepancy which shows up as
a gap between graphics line-scans.
The solution is to patch the code (or data file) that establishes the
linefeed spacing for the printer using debug. What you look for is an:
ESC 32 17
and replace it with:
ESC 32 0F
For example, assuming program foo.exe is the one you want to fix. After
safely saving the original copy, you apply debug to a test copy:
debug foo.exe
S 0 L FFFF 1B 32 17
(debug spits out the addresses that match that three character sequence;)
(assume there is only one, at 1234:5678)
d 1234:5678
(to see what's there)
e 1234:5678 1B 32 0F
w
q
I have used this on various programs, including graphics.com and Ventura
Publisher (that one used a printer driver file) with success. Good luck!

Subject: Help with MicroSoft: Qualification
Date: Mon, 06 Jul 87 23:26:57 -0700
From: Alastair Milne <milne@ICSE.UCI.EDU>
Recently I posted a request for help with what seemed unjustifiably huge
EXE files from combined MicroSoft Pascal and MS C. I have had 2 or 3
thoughtful and helpful replies so far, which I much appreciate. One of
them mentioned that with memory size being what it is these days, code
files of approx. 200K are not really a strain on memory. Which is
perfectly true, so I'd better add this qualification: we need to be able
to deliver up to 10 of these programs, or more, and we'd much prefer
to be able to keep them all on one disc, because, if the user requires,
they can chain among each other, and the support routines are not at this
moment able to do that between discs. Nor, for that matter, am I very
eager to redesign them to do so, since we must assume that the people who
will be using these programs know virtually nothing about computers, and
the less they have to fiddle with the machine, the better. So the problem
is not to fit one of these monsters in memory, but to find around 10 of
them on disc.
Not to keep striking the same sour note, but with this same arrangement
under the p-System, with programs often longer and more complicated
than these, we got 10 of them onto one 360K disc, due to the combination
of code sharing, partial virtual memory, and extremely compact instruction
format. I don't ask for such compactness with native code, but I wouldn't
mind being able to get a similar number onto a 1.2M disc.
Thanks for all the responses so far, and for any more that anybody cares
to send.

Yes, it is possible to use CodeView with Turbo C. You simply
don't get to play with local variables- Turbo doesn't know how to
tell CodeView about them. Global variables and source level debuggin
work just fine, and I have used Codeview to great advantage with one
nasty little problem in a Turbo C program.

I am including a program I have found useful. LPR is a printing utility for
MS-DOS written in C. It prints dated header and trailer sheets with
BigLetter banners, allows multiple copies, various widths & heights, etc.
Standard parameters may be set either in the environment (i.e. "set LPR=...")
or by using command line options.
Two command line options I haven't added that might be nice are:
1) number the pages
2) send printer initialization sequences

Subject: Net mail with graphics
Sending manuscripts through networks has been a problem
since graphics, italics, and special characters are hard to
handle. I developed a utility which allows ChemText documents
containing graphics, equations, etc., to be sent through VAX
mail, BITNET, INTERNET, etc. The recipient also runs the utility
to automatically strip off headers and trailers, perform vertical
and horizontal error checks, and convert back to a ChemText
document. This is a convenient system for dialog involving
drawings, equations, plots, etc. The encoded documents survive
ASCII - EBCDIC conversion. Transparencies or slide masters can
be distributed this way also. I find that when it is as easy to
draw as it is to type, that I use more graphics and the documents
become more interesting to read. I had expected the technology
simply to make it easy to communicate, and did not expect that
it would actually change the way I write and think.
ChemText is the trademark of Molecular Design Limited, 2132
Farallon Drive, San Leandro, CA 94577. This Encode/Decode
utility is not currently automatically provided with ChemText,
you must request it. There is no charge for the utility. Both
Encode/Decode and ChemText run on IBM PC compatible equipment.

We have heard that some people have been having problems ordering IBM
TCP/IP for the PC. Apparently, some of the marketing types got informed
that you had to buy the VM license to get the PC code. We have spoken
with our IBM people about this. They say IBM is *considering* bundling
the PC code with the VM code. Therefore, it is still possible to order
the PC code without the VM product. If you have been told by your
favorite IBM marketing rep. that you must purchase the VM license to
get the PC code, have your favorite IBM marketing rep. contact the

Date: 07 Jul 87 19:11:08 PST
The problem with Procomm(ver 2.4.2) and PC/MS-DOS 3.x is that 3.x deals with
the stack differently the earlier versions. There is a fix floating around
out there somewhere that would be great to get posted to the net. Procomm
checks for the size of the stack using some high and low water markers,
but 3.x isn't always using the same stack...I don't entirely understand
what is going on, but the application and system stacks are separate from
each other (sounds like something creeping in from a multi-tasking form of
the OS??). Anyway, Procomm 2.4.2 blows up using DOS 3.x.

Subject: PCNET
Help. I need an assembler driver (MS DOS 2.0 or higher to run on a
Z-248) for serial and parallel printers (i.e - Genicom, Inteq, ALPS,
Proprinter). I not only need to print, but I also need to know when
the printer is off-line, unplugged, being thrown across the room, etc.
I know some one, some where has written something like this before,
but I just can't find this code (Okay, I really don't know where to
look for it either). Due to hardware limitations, I can not use
interrupts to let the printer call the CPU for more data, so, I'm
thinking that ETX/ACK protocols would be the next best thing to do.
I'll appreciate any hints, comments, and/or answers. Thanks in
advance.
[I don't know how you can do this easily without using interrupts. If
that weren't a factor I would suggest using one of the print spoolers
such as Jspool from Tall Tree or Superspool from AST, but not being
able to use interrupts sure makes the problem difficult. What is PCNET? -wab]

whether or not I can run the silly thing with my CrossTalk. Simply
plugging the box in and loading my script file got me nowhere. There
doesn't appear to be any dip switches in the box, but I couldn't get
a good look at the lower board. If CrossTalk is known to NOT be
an option, is there any shareware / cheap comm software that I COULD

Subject: MKS Toolkit, DOS environment, Freemacs
Is there any way to create/use DOS environment variables while running
under the MKS Korn shell? For example, Kermit looks in the DOS PATH
environment at startup for MSKERMIT.INI. Under the Korn shell, Kermit
only finds my .INI if it's in the current directory. My current
kludge-around is
alias kermit='cd c:/kermit; kermit; cd -'
which works fine except when I transfer files to /foo/bar and forget
they really landed in /kermit.
Similarly, is there any way to run Freemacs from a directory other
than its home directory without defining a DOS EMACS environment
variable? I'd very much like to try Freemacs, but I'm not willing to
give up the Korn shell or use a kludge alias like kermit. A command
line option telling it where to look for its .ed files would do the
trick.

Subject: IBM PC AT motherboard errors / Code 109 / spontaneous reset
From: Burton.osbunorth@Xerox.COM
I need help with a difficult and frustrating hardware problem on my
IBM PC AT (6 MHz, model 068). The system has an IBM EGA, an
IBM disk controller, and an AST ATvantage card for RAM and for
serial and parallel ports.
The system reboots spontaneously, but only very intermittently.
The problem first showed up during a recent heat wave.
If you are a hardware expert or a PC BIOS expert, please read.
Because this problem is so intermittent, the repair shops
really can do nothing.They suggest swapping boards or
running diagnostics. I've run the IBM Advanced Diagnostics
for memory, motherboard,etc., for 24 to 48 hours at a
time. Of course, this turned up nothing.
I've also opened up the system and pushed down on all the memory
chips and other socketed chips. Several people have suggested
that I use a heat gun and freeze spray approach, but engineers
at work have warned me against doing that unless I REALLLLLYYY
know what I am doing. Which I don't.
For $750, plus labor, an IBM dealer will swap out my
motherboard and I get another 6 MHz (whoopie!!) board.
A refurb 8 MHz board is $2100, but I can't do a swap. Some deal!!
And, my problem may not even be on the motherboard. Naturally,
I'd like to fix my problem inexpensively by getting a chip replaced.
This system is used at home, mainly by my wife for her
business. Typically, it is used several days a week, for
several hours at a time, then switched off. If I use it in
the evening, I turn it back on. The system unit is in a
well-ventilated area, mounted vertically, "tower" style.
There seem to be three related problems, which first showed up
during the recent heat wave, when t was over 90 F ambient:
1. The system would simply not boot up at all. The screen
remained blank, as if the monitor was turned on but not the system
unit. After 10 or 20 minutes, sometimes with a few power-on
cycles, the machine would boot up normally, and work properly.
This problem appeared only a few times, and then disappeared.
2. The system reboots spontaneously, often when there is no
keyboard or disk activity. Several people I talked with said
that this problem was common with clones, but not with
genuine IBM AT's.
This problem usually occurs when the machine has been on less
than one hour. Rebooting restores normal operation.
3. The system appears to freeze up, and then shows the message:
System Error 109
on the top line of the display. A power cycle is necessary to clear
up the system to normal operation. At times, the system reboots
spontaneously before displaying this message.
The AT Service manual lists several different error codes for the
motherboard, but doesn't identify the cause. All it says is to
replace the motherboard, which I certainly don't want to do.
The AT Technical Reference manual seems to indicate that Error 109
is related to "Low Memory Chip Select" and this is an error
condition that occurs only during Power On Self Test. I've tried
to read the BIOS and POST listings but I can't understand what
I'm reading. I can't read schematics at all!!
The most direct reference to Error 109 is on page 5-82 (Test 7)
of the Reference Manual. There is a section of code with the comment:
Low Meg Chip Select Test
Test that a write to Address 1B0 0000 does not write to
B000:0, or 1B0 8000 does not write to B8000:0.
The addresses B000:0 and B8000:0 are video memory, and 1B0 0000 is
part of the AT's protected memory, which I have installed.
If you are willing to help, I can save you some scanning through
the BIOS code because I've marked all the pages of the BIOS code
that I thought might apply to this problem.
Ideally, a combination of hardware and software help will
narrow the problem down to a specific chip on my motherboard,
which I can get swapped out inexpensively.

In October of last year, the Spanish Department at Stanford bought

Subject: OCR System Wanted
Dear Info-IBM PC
We are looking for OCR software and hardware which works on IBM PC/AT or
a compatible machine. We want to store English, French and German
books in files to analyze them linguistically by micro computers. Our budget
is 400,000 yen ( about $2700 ) including software and hardware.
Please give us information.

Subject: Print Spooling using DOS function Calls
The DOS (>3.00) reference mentions the use of INT 2f to control a
background printer spooler. As usual, the description is vague,
and incomplete and doesn't seem to work exactly as given. Does
anyone know of a reference, example, etc, that would show how to use
this? Presumably this is the mechanism used by PRINT.COM (.EXE).
Thanks, Joe Smith
