Subject: Improved Patch for Procomm w/ DOS 3.x
Please replace my original patch for Procomm with the one supplied
here. The first patch I developed was really a quick-and-dirty hack
which disabled the stack checker whereas the patch given below leaves
it enabled but removes a call to it in the routine which handles INT
1B (Control Break).
Procomm stack overflow patch:
Symptoms:
Procomm v. 2.42 when running on PC DOS 3.2 and MS DOS 3.x
(some versions) will hang if CTRL-BREAK is pressed. The message
"stack overflow" will be emitted as well as possibly some garbage
before the computer "locks up."
Cure: (Patching procedure)
With a copy of your procomm.exe file (not the original of course) do:
RENAME PROCOMM.EXE PROCOMM.BIN
DEBUG PROCOMM.BIN
E 83D 90 90 90
W
Q
RENAME PROCOMM.BIN PROCOMM.EXE
The above procedure assumes procomm.exe is in the current directory
and debug is loadable (in current dir, or in a dir in PATH). If
anything happens which is not understood, simply omit the W command
above (which writes to disk) and use Q (to quit) instead.
Technical details:
Procomm v. 2.42 has a stack checker which is called on
function entry to insure sufficient stack space for the function to
execute. PC DOS 3.2 and some MS DOS 3.x versions have an "improved"
stack management service which insures that each new hardware
interrupt which occurs is given a new stack to use in its interrupt
service routine. The size of these stacks and their number are
settable with the CONFIG.SYS option STACKS=n,s (number, size).
The "stack overflow" error discovered by procomm occurs
because DOS, in response to the CTRL-BREAK interrupt, has switched
stacks to one from the DOS stack pool, and Procomm is assuming its own
stack is still in use. The limits used in the stack check routine
fail because the DOS stacks are normally much smaller (512 bytes by
default) than the stack used by Procomm.
The easiest way to solve the disagreement about stack
ownership is to remove the call to the stack checking routine from the
interrupt handler for CTRL-BREAK. The above patch does exactly this.
Procomm is otherwise happy to use the DOS supplied stack since
servicing the BREAK request does not require lots of stack space.
There may be another option for DOS 3.3 users: It is possible
with DOS 3.3 to disable the DOS stack swapping by putting STACKS=0 in
the CONFIG.SYS file. I have not tried this, but my understanding of
the problem indicates this should also work.

Subject: Deb2asm
To: info-ibmpc-request@c.isi.edu
I would like to contribute the appended program DEB2ASM to the library.
DEB2ASM converts a disassembly output from the DOS DEBUG program to a more
regular and (hopefully) more legible format. The source is in TURBO pascal
and is packaged with an I/O -include- file. You will need SORT.BOX
(Borland Turbo Toolbox) or provide your own sorting routine.
The program produces labels from the hexadecimal offsets (both code-labels
and variables) appearing in debugger output and constructs a cross-reference
table with declarations of variables in the format:
V_XXXX LABEL <TYPE> ; R_XXXX, R_XXXX, ...
where <TYPE> is BYTE, WORD or DWORD
and the R_XXXX's are the locations where the variable
occurs in the code.
Usage of a memory location as more than one type (referenced both as a
BYTE and as a WORD for instance) results in multiple entries in the this table.
However, segment declarations are not generated and intersegment references are
not detected (this is an invitation, of cause).
Useful for deciphering ROM's of which the manufacturer failed to publish a
proper listing (for instance my PARADISE Graphics card, which makes improper
use of the NMI line (IOCHK) on my PC).
I also managed to regenerate the missing part of the AT BIOS Listing this way
(PC-AT Technical Reference, POST6 routine). I never saw a supplement from IBM
here.
If anyone is interested (and if it is not illegal) I can also post it as an
example of the ouput generated by Deb2asm.
Please let me know,

===========================================================================
CCMD
TOPS-20 COMND JSYS EMULATION PACKAGE IN C
INTRODUCTION
CCMD is a library of user and program interface routines, written in C,
based on the TOPS-20 COMND Jsys.
CCMD provides a means for prompting and for parsing commands in various
forms (keywords, switches, fields, numbers, dates and/or times, tokens, single
characters, file names, user names, group names, paragraphs, lines of text,
quoted strings, confirmation, noise (guide strings), etc.). CCMD provides
incremental help. At any point during a parse the user can type a question
mark and the parser will provide a brief help message describing possible
reponses at that point in the parse. When the user types an escape the parser
will try to complete the command if a unique completion exists or it will give
as much partial completion as possible and wait for more input from the user.
CCMD also provides a simple set of line editing control characters to
delete characters, words and lines, and to redisplay command lines or clear the
screen. A limited history mechanism is also provided. The last command typed
can be recalled by a single keystroke (^H).
SUPPORTED SYSTEMS
CCMD was developed at Columbia University by Andrew Lowry and Howie Kaye
under 4.2BSD and later under DEC Ultrix 1.2 and MS-DOS.
CCMD currently runs under UNIX BSD 4.[23], Ultrix 1.2, SysV, SunOS, and
MS-DOS 3.1. We are planning on porting it to HP-UX and VMS sometime in the
future.
MAILING LISTS

Subject: TurboC "bug"?
I would like to thank J P Nelson & Billy Vol 6 #50, for putting the TurboC
patches on INFO-IBMPC. Here is another little problem, which is still
not solved by the patches. Maybe it is my understanding of the "double"
type usage: Anyway, here it is, from the TurboC User Guide pg85, and subsequent
paragraph, mentions changing the example by replacing the int a,b; by float
Works fine, except I then went a step further and replaced float by double.
Compilation is fine, on run, if you enter 10.0,3.0 you get the magic
statement: "underflow" (it was overflow before I put the patches in)"
main()
{ /* modified as per page 85 TurboC user guide */
/* This works fine */
float a,b,ratio,prod;
printf("Enter 2 numbers: ");
scanf("%g %g",&a,&b);
ratio = a/b ;prod=a*b;
printf("Ratio is %g product is %g\n",ratio,prod);
}
main()
{ /* modified as per page 85 TurboC user guide */
/* This doesn't. Compiles fine, but
fails on run time with errors: underflow */
double a,b,ratio,prod;
printf("Enter 2 numbers: ");
scanf("%g %g",&a,&b);
ratio = a/b ;prod=a*b;
printf("Ratio is %g product is %g\n",ratio,prod);
}
All help gratefully acknowledged. Maybe it's the scanf function
which can't handle "double"?

We have a version of TurboC that we are thinking of using on a project. If

Subject: DRIVPARMS
Some time ago it was mentioned that PC/DOS would also allow use of the
DRIVPARMS entry in the config.sys file.
I used it successfully with V3.2, after having added a 3.5" drive to a
xt clone. I have discovered that it doesn't work with PC/DOS 3.3. We must
realize that the changes to the drive table are ONLY required so that FORMAT
will work properly. When you stick a diskette in the drive, DOS reads the BPB
from the first sector, and modifies the drive tables accordingly. Format, of
course uses the default for the drive.
Interestingly enough, the entry for DRIVPARM is still present in IBMBIO.COM.
They have either disabled it, without actually removing from the list of
acceptable responses, or the format has changed. DRIVPARMS is not mentioned
in either the DOS manual, or the Tech Ref manual, as far as I can see.
Does one have any info about DRIVPARMS under 3.3, or failing that any ideas
about how one could path the default drive tables ??? I realize that I could
use driver.sys, and that does work, but who needs another device driver eating
up memory ??

Both _Byte_ and _PC_ magazines mention the use of the cache. The
cache uses the above-640k memory on the PS/2 machines.

There should be no improvement at all on the first read, but
subsequent reads will be considerably faster (80% should be close, but
I suspect it's a little lower than that). There should be no problems
at all with using the cache on AT's: if the PS/2 machines will boot
and run DOS 3.x, then they're close enough to use nearly everything on
the AT's, and vice versa. The structure of both machines is really
pretty close, at least so far as disk I/O goes.

Big Blue is not trying to give the PS/2 something extra. Check out
the average access times on the drive on the model 50! I believe it's
something like 80ms, which is SLOW! I think IBM had lots of extra XT
drives they wanted to pawn off. If they didn't use a cache, user's
would tear their hair out waiting for things. As it is, the model 50
should have at least a 40mb drive, not just the 20 they give you. IBM
is just trying to make up for some really stupid moves.
The program should work on all DOS 3.x's, and maybe even 2.x. I would
suspect the cache program traps BIOS calls to read the hard drive;
that's easy enough to do and will work even with other drivers
included.

You'll have to forgive any small technical inaccuracies here. I
haven't had the chance to more than glance at the real PS/2 machines,
but I have read a good deal about them. My personal opinion is that
IBM is blowing it -- the machines (model 50+) are little more than
AT's with a faster clock speed and a better bus, at least until OS/2
comes out. Want to bet on how long that takes? I know IBM is too big
to get tossed out of the race, but they sure seem to be trying hard.
Time will tell!

A note for MS Ftn 4.0 user's, there is a bug in the eof statement
such that it leaves two bytes on the stack when it returns. Having
programmed in pascal recently I tried to use the EOF statement in an
if statement to simulate a WHILE NOT EOF loop. The result was a
stack overflow error at runtime. I tracked the bug with Codeview and
it showed the stack pointer changing by 2 bytes after every call to EOF.

Subject: Recovering backed up dBase files without last disk
To: info-ibmpc@c.isi.edu
Recently one of our users lost the last disk in a set of disks
containing her hard disk backup. When she tried to restore these disks
following a hard disk crash, the restore wouldn't work. Most of these
disks contained one large dBase III Plus .dbf file.
The lost disk was #13 of 13. We tried to fake it as follows: Using
Norton's Utilities, Adv. Ed., we edited the BACKUPID.@@@ file on disk
#12 such that the backup header became FF0201. FF is the required
header representing the last disk, and 0201 designate #12.
We then went into the DATA.DBF file on disk #12 and went to the end of
that file, deleting the data in the last record visible, and replacing
it with an "end-of-file" marker. In this case, dBase appeared to
require two right arrows for this marker, produced with the characters
of 1A1A.
Everything seemed fine at that point, but the restore still backfired
on the 12th disk. Can anyone tell me what we've overlooked? I'll post
the result to the net if it works. Thanks.

Subject: LaserWriters .vs. PC software.
We have a LaserWriter attached to a PC-clone via RS232C (soon to be
networked, in some manner, but will remain serially attached). We
are using Wordstar 4.0, Wordperfect, TeX and other stuff that emits
straight PostScript. Problem is that Wordstar only uses Diablo
emulation mode, while everything else sends more or less well-behaved
PostScript (less, in the case of WordPerfect). All this seems to require
continually changing that silly little rotary switch in the back, to switch
from Diablo emulation mode and back again.
I can't beleive that there isn't a hook into that emulation mode from
LaserWriter PostScript, except I can't find it in my (rather old)
documentation. Anybody know what it is: i.e., how can I get at the
Diablo emulator without touching the rotary switch? The alternative
seems to be writing a Diablo emulator in PostScript; if my first
question can't be answered, does anyone have such a beast that they
would be willing to share?
In a related question, it doesn't seem like it would be too difficult
to write a replacement RS232 driver for PC's that would honour
XON/XOFF and DTR protocols, and would pop up little window on the
screen to display messages from the LaserWriter. Anyone know of
such a thing?

I have an old version of DESQVIEW (circa 1.1), but it doesn't allow
communications to run in the background. I would be highly interested
to know if this is an errant posting (the comm line would be hard to

Subject: MS C compiler V 4.00 Problem
I started recently to work with the Microsoft C compiler V 4.00,
but, unfortunately, when I tried to use the library function "printf",
the linker (MS V 3.05) claimed that "printf" is an invalid object code.
the same error was encountered when I tried to compile with the /Zi option,
even for the minimal program: main(){}
The message of the linker was this time, for example :
Invalid object module
Input file: TRY.OBJ(try.c) pos: 10E Record type: 8C
Could you help me find out what is the problem?

Subject: Problem with Turbo Pascal and 2 printers
I have just started using Turbo-Pascal in a Radio-Shack Tandy PC-AT.
I would like to know how I can access two printers ( connected to S-8 and
S-10 )? I tried the "writeprinter" routine given in Turbo-Pascal
book, by alternating the values in the DX register between 1 and 0.
It does seem to print, but the characters are sometime printed twice
and it is extremely slow. Typically, it pauses about 10-15 seconds
between each character printed. I would really appreciate if any
readers can supply a procedure I could invoke before printing
on either printer. Thanks for the help.

I am curious to know what the maximum usable number of active nodes in

The most I have heard of is several dozen; certainly less than 100. A
salesman is proposing a 300 node LAN as a feasible solution to a potential
customer. Surely the man is dreaming.

Subject: question about interrupt driven LAN protocol
Date: 16 Jul 87 19:14:05 GMT
I am developing a simple LAN program. I want it to be interrupt
driven. In the first phase, I will be having only two Ats to work with.
One will be the master and other the slave. I want to be able to perform
R/W on the slave's disk. How do I go about doing this. Let me give you
some specifications.
The program is to be developed on an AT under MS-DOS. Program will be
written in `C' using Microsoft's `C' compiler 4.0. The machines are to
hooked up by standard RS-232 cables.
Questions:
How do I disable the slave by sending an interrupt form the master, to
interrupt its current task and then execute the command from the master
on the slave (eg. write to its disk). After the command execution has
been completed the normal task should be resumed.
How to make the slave respond to an interrupt sent thru the port, seems
to be a problem to me.
Please respond by sending e-mail to dipto@umbc2 (BITNET) or posting an
article here. Any suggestions, guidelines will be welcomed. Thanks to
all of you in advance. I am a Unix person; and haven't been in touch
with the PC world until this project came up. So long for now ...

I am having a strange problem with "Prt Sc" on an IBM-PC/XT running
PCDOS 3.3. My printer is a NEC PC-8023A. When I copy files to PRN or
use control-P it works fine. When I use Prt Sc to dump the screen to
the printer, everything prints on one line. It's as if the DOS Prt Sc
function is stripping all line feeds or simply not adding them. Has
anyone else had this problem? I don't want to turn on the printer's
auto line feed on receipt of carriage return because that would result
in double line feeds when copying a file to PRN.

I need to set a machine round-off constant for a public domain code

version of what is today known as DGEAR, an ODE integrator. In the
program which runs on a Cyber 7600, a value of UROUND=7.105427406E-15 is
set. The comment also says to use UROUND=9.5367E-7 for short precision
on IBM 360 or 370. Another name for this variable is SEPS. Does anyone
know the correct value for an IBM-AT or any way to determine it since
neither value above works? The constant is used to compare with desired
tolerance.
