Subject: Re: $25 network
Actually, $26.50 with postage! It works, too. UNLESS you have a modem
on COM4 the way I do. Telephone support has suggested several cures,
but I still have to unplug the modem to use the network on COM2. If
anyone has solved this problem, I would certainly appreciate hearing
about it. NB, my mouse is on COM1. There are no TSRs running that use
COM ports. The problem is almost certain to be a conflict on IRQ 3.
Thanks for any help!

A good accelerator card and a new motherboard may cost about the same
amount. But, it is not a fair comparison. Replacing the motherboard
has a lot of additional costs.
If you replace the motherboard, you must replace all RAM, the Floppy
Controller, and the Hard Disk Controller. If your keyboard doesn't have
an AT switch, you must replace it. And, you will probably also loose
all of your COM: ports. Don't backup your hard disk with LapLink,
you'll never get the data back. (Unless, of course, you want to buy new
COM: ports).
[Isn't LapLink a program to transfer data/programs from one computer to
another? I don't recall it being a backup program... gph]
All of this will run you around $800.
Let's not even talk about your slow hard disk or double density floppy
drive.
Sure, the motherboard is a much better option, but at these prices you
could almost by a new 386 machine.

Subject: Re: disable control-C
There exists (somewher on SIMTEL20?) a resident program (in CADEL.ZIP)
CADEL.COM that "eats" control-alt-del, control-c and control-break.
This program may be specified as the first program (to load) from
AUTOEXEC.BAT (or with some utility I remember for that purpose from
CONFIG.SYS). This disables the keys. BREAK OFF from CONFIG.SYS or DOS
only prevents a break during all DOS operations except during keyboard,
screen, printer or aux input and output operations. OFF already is the
default.
[CADEL may be found as PD1:<MSDOS.KEYBOARD>CADEL.ZIP gph]

Subject: Disable Ctrl-C
The solution for this problem is quite simple and elegant. In your
config.sys add a 'shell=' directive, specifieng the path to your
command.com. In the end of the parameters list add 'nul'
Example:
SHELL=c:\command.com/p nul
*most* versions of DOS will start command.com reading and writing from
the nul device. Do not forget to issue
ctty con
at the end of your autoexec.bat.

We had a major windstorm in St. Louis today that caused many fires and
caused many power line problems. I had a succession of dropouts while
working on my computer. A couple of times the partition information on
one of my hard disks was damaged. Luckily, I had purchased Peter
Norton's Utilities within the last week. Since I was using Image and
Disk Doctor, the disk was restored in little more time than it takes to
boot.
Later that evening, I saw a spectacular electrical fire atop a utility
pole. A 2-inch diameter spark was sputtering continuously, as bright
as a streetlight. It seemed to be located where a cable sat on top of
an insulator, so perhaps the insulator was burning! -David-

Subject: Program input/ouput capture
Gray Cluley <gm_cluley@prime2.bristol-poly.ac.uk> asked about capturing
program input/output:
Dear Gray Cluley,
To solve your problem you may obtain the program PRNDSK from SIMTEL20
(probably a .ZIP file, but I don't know which directory). This is to me
the nicest and mostly extended resident program to capture printer
output to another device (disk). If you load the program, start your
application and press Ctrl-PrtSc (for printing anything scrolling over
the screen) all screen contents (input and output) will go to a
specified device (diskfile).
I hope this helps,

E. Cadima asked about a utilitie to read n characters from a file starting

rf file 10 100

In a UNIX system you can combine the head and tail programs to obtain
the desired result.
In any case the following C program should work in MS-DOS, OS-2 and
UNIX systems (I have tested with Borland Turbo C++):

Dear Vincent Chan,
I do not know the configuration of your system, but I assume strongly you have
some SHELL statement in your CONFIG.SYS. If you do not have included the '/p'
like in: 'SHELL=C:\DOS\COMMAND.COM C:\DOS /E:1024 /P' then AUTOEXEC will not
run. You must explicitely include the '/p' option to have AUTOEXEC run.
[The /p option also makes COMMAND.COM permanent... Kinda like a TSR
but not really. gph]
I hope this to be the solution of your problem.

I have an Adaptec ACB-2070A controller in my IBM-PC/XT. Recently it
has become necessary for me to swap out the 10 mHz turbo motherboard

problems with the Adaptec creating files marked as "cross-linked" by
CHKDSK. At the same time, the floppy disks perform flawlessly at 12
mHz. Does anybody have any suggestions to help "persuade" the Adaptec
to work properly at 12 mHz.

Subject: Help! Problems.
I have a gateway-2000, 20 MHz 386 system, and have been using a wefax
board (and program) for 6-7 months with no problems. This Christmas I
got a few accesories that I tried to install, first a second hard disk,
(that went ok), then I switched DOS versions from 3.3 to 4.01 (on the
first logical drive of the first drive, but nowhere else (probably
mistake #1). Then I installed Windows 3 (seemed to go ok). Then I
tried to run my wefax program under Windows 3 (it bombed).
At this point (before rebooting the next day), I tried to install a
new computerized weather station board, but the computer would not even
go through its initial checkout let alone boot up (nothing appeared on
the monitor)! I pulled out the new board, and although it went through
the checkout, it was going VERY slow, and once through, as it was
beginning to go into the bootup routine it gave an "XCMOS checksum
failure" error message, but then went on to boot normally.
Confused by this, but remembering that a few days earlier the system
had lost a few days on its clock, I thought that perhaps the CMOS
battery was dead, so I checked, and sure enough, it had lost all
knowledge of my second drive. I replaced the battery, and reprogrammed
in the drive data, but still got the XCMOS error.
I also found that my modem was no longer working properly. I then
decided to convert over all the drives to DOS 4. Hours of file
copying, fdisking, and formatting later, I finished, and on rebooting,
got no XCMOS error. Now I tried to run my wefax program again, and it
bombed again (not through windows this time), and after rebooting I had
the XCMOS error back again. I assumed that my wefax program was not
DOS 4 compatable, so I decided to go back to DOS 3.3. Hours later,
back with DOS 3.3, I still get the XCMOS error.
Somewhere along the line, however, my modem came back to life, and the
computerized weather station program and board began working, so
everything is back to normal except that my wefax board was shot (I
have tried it on other computers, and found that a few chips had been
destroyed. I fixed the board and it now works), and my computer still
gives the XCMOS checksum failure message. The CMOS setup seems to have
the proper information (at least with respect to time, drives,
monitors, keyboards, etc. It doesn't go into memory allocation,
clocks, etc.). Anyway....
* Does anyone have any idea what could have caused all this?
* Could software incompatabilities cause a board to burn out?
* What does the XCMOS error refer to? (Also, how does one access
the XCMOS memmory, ie where is it in memory, or is it accessed through
ports somehow? And, where is/are the chip/chips located, on the
motherboard, drive controller board or video board {I assume that it is
on the motherboard, except that if I remember properly I think I found
the string message for the error in a rom area associated with one of
the accessory boards, can't remember which one})
* All three boards I was having trouble with use Ports (different
ones) and/or interupts, particularly timer interupts. I was making my
first attempt at using enhanced mode to try some multitasking about the
time the troubles began. Do the ports behave any differently in
enhanced mode such that a conflict may have appeared that would not
have existed in real mode? I have read postings about windows-3 taking
control of the timers, could this have interfered with a data
acquisition board which uses D-A's and A-D's in conjunction with
timers (ie, if the timers are messed up, could a D-A develope too high
of a that could have burned out the chips?
* When I first got my computer, the CMOS setup described my 65 MB
RLL drive as a 40 MB drive. This seemed strange, but I had read about
RLL drives functioning by lying to DOS, etc, so I left it alone. When
I reprogrammed the CMOS to put in the second drive, I likewise lied
about it, but have since changed both to reflect the true size of the
drive. How might this have affected my problems? Which should it be?
What is the true dos 3.3 size limit, I have heard 32 MB, but nominal 32
MB is really around 33 MB. Some of my partitions have 33 MB actual, is
this a problem for dos 3.3?
* Is there more than one CMOS chips? Ie, one for motherboard and
others for the disk and video controller boards?
Any and all suggestions and/or explanations will be appreciated.
Thanks.

getting a board based on the 16450 UART if you require 9600 baud or
greater speeds. However, asking most mail order houses (even their
tech support lines) what serial chip (never mind "UART") their boards
are based on usually gets confused mumblings, or such gems of wisdom as
"the usual one."
Can anyone either
1. Tell me where I can get a serial board based on the 16450 (or

2. Describe their experiences (good or bad) they have had operating

Has anyone been successful in running windows under VPix?
I am running VPix version 1.2 on Interactive UNIX 2.2 and I can sort of
get a version of Windows/386 (version 2.1) limping under VPix, but it
tells me that my machine configuration has changed (after waiting for
about two minutes for it to start up) and I can't reinstall it because
the setup program tells me that I don't have a 386 machine (VPix
presents a real mode machine - although the VPix documentation says
that it "supports popular PC aplications and DOS facilities that run on
IBM PC AT-compatible systems" - which sounds like 286 machines).
When I start up Windows-3, I get the startup screen and then VPix
crashes with a "General protection fault, cannot emulate instruction"
message. The VPix version 1.2 release notes say that "VPix has been
made less prone to failure when using the serial mouse. This will
alleviate problems seen when using the Microsoft serial mouse with
Microsoft Windows." This leads me to believe that there is a way to
get windows running on VPix.
Any experiences would be appreciated.

Summary: Reposted by Keith Petersen
The 9.x release of the Clarkson collection of packet drivers is now
available from SIMTEL20:
pd1:<msdos.ka9q-tcpip>
DRIVERS.ZIP Clarkson packet drivers wo/src for KA9Q TCP/IP
DRIVERSS.ZIP Clarkson packet drivers w/src for KA9Q TCP/IP
Please discard the 8.x release, as the -n switch is broken in it.
The packet drivers are for MS-DOS, and serve to hide the difference
between network cards, and allow multiple protocol stacks to access the
same card. Most often people are interested in running Novell's
Netware and TCP/IP at the same time.
Summary of changes in the 9.x release:
The -n switch works again. It was broken in the 8.x release. Bugs
fixed: ibmtoken, others.
The Clarkson packet driver collection
Availability
The Clarkson collection of packet drivers is available by FTP, by
archive-server, and by modem. They come in two flavors -- executables
only (drivers.zip), and source+executables (driverss.zip). All of the
following instructions apply to both drivers.zip and driverss.zip.
Mail:
I distribute the packet drivers on two 360K 5.25" disks, or a 720K 3.5"
disk. I charge a fee for the service of copying and mailing these
disks. You can send me a check for $20, or you can send me a purchse
order and I will bill you for $22. NY residents add 7% sales tax,
overseas orders add $3 for shipping. If you send a check, please be
sure it is in US dollars -- the bank charges me $15 to convert checks
drawn in foreign currencies.
