-----------------------------------------------------------------------
WHAT IS COHERENT?
Coherent is a multi-tasking, multi-user operating system for IBM
PC's and compatibles. It will run on most systems with a 286,
386, or 486 CPU. Coherent closely represents the Unix operating
system, but, it is not Unix. Coherent appears to be very similar
to Version 7 Unix, or for those of you that have not had the
pleasure, close to System 5 Unix. Coherent includes uucp (Coherent
to Coherent Copy) :) and many more functions you would expect with
Unix. Coherent is small and simple, easy to maintain, and does not
require extensive CPU resources to operate well. It does not have
network nor X windows support, and does not require an AT&T
license for Unix. It is as advertised, a quick, elegant Unix-like
multi-tasking, multi-user Operating System, with good
documentation.
WILL COHERENT RUN ON MY SYSTEM?
Coherent runs on just about all 286-386-486 systems. To list them
here would make this document far too lengthy. It is suggested
that if you are in doubt, buy Coherent, and when it is almost
beyond a doubt that you can not run Coherent on your machine, to
return the software and documentation to the the Mark Williams
Company within 60 days for a full refund as per their policy.
WHAT INCOMPATIBILITIES ARE KNOWN?
IBM XT compatibles will not work, since the Coherent version 3.2
operating system uses the 286 protected mode. Coherent version
4.0 only works on 386 or 486 proccessors and operates in the 386
protected mode.
Coherent will not run on an AT&T 6300, IBM PS/2 model, or with the
Western Digital WD1004-27X (XT) or other XT controllers. Coherent
exhibits a slight problem with some 386 AMI BIOS, whereas Coherent
requires a cold boot (hit the reset switch, not CTL- ALT-DEL) to
boot Coherent after previously running DOS. The latest revisions
of the AMI BIOS may not exibit this problem.
CAN I STILL RUN DOS?
Yes, Coherent can reside on a disk partition separate from DOS,
and likewise DOS on a partition separate from Coherent. You can
boot either one at boot time via a "boot strap" program. They
will not run concurrently however. DOS file systems are available
to Coherent with the Coherent DOS command, so files can be
transferred from DOS to Coherent, Coherent to DOS.
WHAT ABOUT TECHNICAL SUPPORT?
It is generally felt that Mark Williams Company provides excellent
technical support of their software within the U.S.A.. They can
be reached via phone (708) 291-6700, or email:
uunet!mwc!support (General uucp address)
support@mwc.com (Internet address)
mwcbbs!support (from your system directly to the uucp connection
they provided by the Mark Williams Company)
WHAT REVISION IS COHERENT?
Coherent is offered in two revisions. Revision 3.2 will run on
systems with a 286 or higher processor, but does not take
advantage of the 386 architecture, and has the 64K executable and
64K data limits. Revision 3.2 is the last revision of Coherent
for the 286 protected mode OS. Bug fixes will continue to be
posted to mwcbbs to support customers of the 3.2 version.
COHERENT 4.0 was announced in May of 1992, and is targeted for the
386 and 486 processors. This revision does not have the 64K
limits of revision 3.2, but, still does not include a virtual
memory system that swaps pages out to disk. See the 4.0 specific
FAQ posted with this FAQ for more information.
Both versions of OS are available at $99.00, and updates from 3.2
to 4.0 are now priced at $79.00.
HOW MANY PEOPLE RUN COHERENT?
The Mark Williams Company has stated that the sales volume has
passed 40,000 copies since its introduction to the market in 1990.
CAN POSTINGS BE MADE IN THIS NEWS GROUP (COMP.OS.COHERENT)?
It is somewhat accepted that source for Coherent will be posted in
this news group occasionally. Keep in mind that large postings
cost money to those that pay for telephone and connect time, so
perhaps a short posting to query general interest should precede
the posting. Direct mailing should be used if there is small
interest, and a posting to archive sites such as raven.alaska.edu.
If the interest is overwhelming, a posting to this news group may
be in order, along with posting to an archive site such as
raven.alaska.edu. Posting to this newsgroup has been a topic of
constant debate... :( We hope to have a source news group for
coherent, yet another topic of debate... :)
PUBLIC DOMAIN SOFTWARE:
Several public domain packages are available for use on a Coherent
machine. These range from improved mailing packages and spread
sheets, to at least four news programs, such as bsnews, cnews,
gnews, wnews, along with readers such as rn, tass, tin and more.
WHERE DO I GET THE PUBLIC DOMAIN SOFTWARE?
There are several ways to get public domain software:
1. Mark Williams Company bbs (mwcbbs)
2. FTP sites
3. Mailserver (ListServ@IndyCMS)
4. The OZ / NZ Coherent Users Group
5. The Pacific Australian Coherent Users Group
MWCbbs (mwcbbs)
Access information on the mwcbbs is included in the documentation
provided with Coherent. In short, it is a uucp site with public
domain software as well as updates to the Coherent release, along
with Coherent news (not usenet) and a "home" for all Coherent
sites to uucp to. For most of us, that is a long distance phone
call, as the Mark Williams Company is located in Illinois.
FTP sites:
Jay C. Beavers has been keeping the Coherent Archives for quite
some time on the ftp site orca.alaska.edu, and has moved these to
an Ultrix machine for better access (raven). When a previous ftp
site was no longer available, Jay quickly put raven into action.
Hats off to Jay!

MailServers:
ListServ@IndyCMS has been offering a mailserver service since
before the start of comp.os.coherent. It is a gateway between two
nets:

Coherent@IndyCMS is bidirectional gateway between the ListServ
list Coherent and Usenet newsgroup comp.os.coherent co-owned and
coordinated by John Harlan and Phil Corporon. All original
postings to comp.os.coherent Usenet group are automatically
distributed to the ListServ list, and everything posted to the
ListServ list Coherent, is automatically posted to
comp.os.coherent on Usenet. John Harlan humorously adds: "And all
without mail looping :-)"
To get a list of Coherent files from ListServ, mail the ListServ
mailserver as follows, with the contents of the message being the
mailserver command:

HEATED DISCUSSIONS OF THE GROUP:
Mark Williams Company has a patent on bit ordering, which is a
software patent. Most think that this is obvious art in software,
and should not be patentable, not to mention a move in the
software world (i.e., FSF) that "software" should not be
patentable in the first place. The Mark Williams Company has
committed to comment on this some time in the future.

Subject: Re:Coherent FAQ, General Information
After a long dry spell of my postings not making it out, here
are the FAQs. I realize I am less than punctual about posting
these, but, after my upstream site changed news host names,
not posting one made it out of here for nearly 3 months. We
are not what you would call a high volume site, although
incoming is usually near 40 megs a day, our outgoing doesn't
make it past two or three postings a week. My last posting
from an Internet host was unusual. Since I pay $$$ for time
on that host I never read news there, and so I never had an
idea that my postings never made it upstream. However, I
have always verified that they were going to my site
(minuet.omc.com) which is a down stream leaf node, and so I
thought all was well. It wasn't. So if you are reading
this, the FAQs should again start coming out in a semi-punctual
manner, well, maybe even more punctual manner.
The current FAQs are at REV 2.3. When I make a change to any
FAQ, all the REVs roll to reflect them as a "set". This set
had some formatting corrections and some input from Robert
Chalmers is OZ. I appreciate the updates and corrections!
I have received some offers for help with the FAQs, and I have
forwarded my ideas to those people. I hope the quality and
consistancy of the FAQ can be improved with a second set of eyes
and effort.

-----------------------------------------------------------------------
MODEM DEVICES:
Q: What devices should I use with a modem for dialing in / dialing out
A: For dialing in you should use a device with modem control. For example
com1r or com2r. That is important to ensure that when the calling site
dropped carrier, that also at your site SIGHUP is sent to already running
processes, to ensure that the modem hangs up (dropping DTR) and a new
getty is opened on that port to enable further logins.
For dialing out or local terminals you do not need modem control
Also you do not have to worry about cabling problems, just use some
of those null modem cables available in most computer stores.
REMOTE LOGINS:
Q: How do I enable logins via modem to my machine:
A: I assume that modem is set to AUTO-ANSWER (ATS0=1) and the cabling
is ok.
Edit the file /etc/ttys. Here an example for com2:
0rPcom2r
0 = not yet enabled (enable = allow login, run getty)
r = remote access (will enable asking of a password
for remote-access (see /etc/passwd)
Why ? System security, additional password
P = speed (your modem is connected to the computer)
P = 9600 Baud, I use this for my Telebit Modem
com2r = device with modem control, when CARRIER is lost it
will sent SIGHUP to all processes running on that
line and will also drop DTR so a modem hangup or
a modern modem does a hardware reset.
Now type the following:
enable com2r (for Coherent 3.2 that's enough)
kill -1 1 (Coherent 3.0.0 or 3.1.0, Process INIT will start
a getty on com2r)
FAST MODEMS:
Q: Can I use fast modems with Coherent 3.2?
A: Yes you can. But you must think about the following:
a) maximum Baud rate between modem - machine is 9600 Baud
(Coherent as a multiuser/multitasking environment is
not fast enough for 19200 Baud)
b) cps-rates in transfer depend on modem/method
calling into my machine (T2500) with a USR, using sz for transfer:
480 cps to 600 cps (compressed, uncompressed files)
calling out with uucp (T2500):
860 cps
The rate may differ if you use a slow 286 or 386. The above results
were yielded with a 386/33.
SIMULTANEOUS USERS:
Q: I want to use Coherent 3.2 as a multiuser operating system. How many
users can work with it at the same time ?
A: Now 11 User:
console : 1
com1 : 1
com2 : 1
Multiport : 8
--------------
11
USENET NEWS SOFTWARE:
Q: Is there any Net-News Software for Coherent ?
A: Yes, there are several packages available:
CNEWS - the famous package
difficult to install (although there is a nice installation
script in the Coherent version). Only for advanced users !
Has no reader !
WNEWS 3.0 - News for MINIX, ported to Coherent
based on BNEWS - small, not bad
Has no reader
rn
the well known newsreader
tass
curses based newsreader. Nice, but you should not have
too much groups or articles in /usr/spool/news.
bsnews
small news package for receiving news via email
and others...
EMAIL PACKAGES:
Q: I do not like Coherent's mailer. What can I use instead of it ?
A: WMAIL 3.63 - a minix port, MAILX-clone
comb 1.29 - curses based mailer, nice interface
You should ensure that in both cases you have smail 2.5 as
a smart-mailer that understands domain addresses.
smail 2.5 is already in Coherent 3.2
THE 64K QUESTION:
Q: Does Coherent really have a 64 kb limitation ? I want to port
the GNU-C-Compiler and compile big programs.
A: Coherent programs are limited to 64 K for code and 64 k for data
and stack. The limit is not in the compiler, it's in the kernel
or at least in the actual system design. No process can exceed this
limitation.
But Binaries in Coherent are about 40 % smaller so big programs
for "Real-UNIXES" may also be portable
COMPILER HINTS:
Q: I write a C-program that seems to be ok but it still core dumped.
Is this a compiler error ? Is my program wrong ?
A: If a program needs a lot of space for local data (resided on the
stack in most cases) then the maximum size for the stack may be
exceeded and your return addresses or other important things were
overwritten.
With the program fixstack you can increase the size for the stack
(and also cut the space for data)
Try size my_prog before and after fixstacking to see the difference.
HARDWARE CONFIGURATIONS:
Q: What hardware (Motherboard, hard disk) do I need for Coherent ?
A: Difficult question. Minimum is a AT 286 with 640 KB RAM and a
hard disk (MFM,RLL,ESDI,SCSI (some), IDE (some)) with at least
10 MB free disk space.
Nevertheless Coherent is not the fastest operating system, so
a 386 with at least 25 MHZ and 4 MB RAM and a fast hard disk
(a hard disk is always too small !!!!) is the minimum config-
uration for a usable multi-user-operating.
TERMIO HINTS:
Q: I compiled a program that uses termio but it did not work.
A: The termio in Coherent (at least 3.1.0 and the first 3.2.0) did
not work in all cases. So try the sgtty, that works fine.
When porting programs try to find the -DBSD-parts. There you will
find in most cases the sgtty-parts you need for porting.
CURSES:
Q: I compiled a program that uses curses but the screen sometimes get
garbled or the machine seems to hang
A: Maybe you still have an old libcurses.a. Replace it with a newer
copy.
MORE UUCP:
Q: I often loose email or files after receiving them with UUCP.
A: Try to get the newest UUCP-update from MWCBBS. The old packages
still have some problems. Check the permissions, at least for example
with comparing them with those on your original diskettes.
Check also the permissions of the needed directories.
In /usr/spool/uucp/Logs./uucp-program you will find the "hints" of the
"uucp-program" (uucico, uucp, uux,uuxqt) what goes wrong.
In Coherent 3.2. you have the program uucheck that will check your
uucp-installation and is also able to "fix" problems. But you have to
run it twice if you run it as root because the first time it creates
the needed directories and the second run sets the correct permission.
Q: I am having a problem connecting to uucp sites not running Coherent
after updating to Coherent 3.2. The error looks like a parity
problem, with an {expect} / {actually got} output like:
uu315323t 342og310n: (With backslashes before the numbers)
Again, get the latest UUCP package from MWCBBS. The 3.2 Coherent
release may exhibit a parity problem which is cured with the latest
uucp release.
HOW TO CREATE A BOOTABLE >>>R/W<<< FLOPPY from Coherent
From: Peter Fillingham fillingham@att.com
The COHERENT Operating System Release Notes (Release 3.1.0) along with
the main manual suggest ways of creating a bootable floppy. One
difficulty of this procedure is that, after producing a bootable
floppy, one can't write to it ! The following shell programs are
suggested as a way making a bootable floppy, and below is the fix
recommended by mwc for making the bootable floppy system read-write.
(0) first boot your system from your hard disk, login in as root,
use mkdir to make a convenient subdirectory [e.g., /bin/temp ]. cd to
/bin/temp. Place disk #1 of your mwc original floppies in drive A:,
then enter
dd if=/dev/fha0 of=cohboot count=80 bs=30b
Run it in the background if you wish [follow the above line with an &;
use ps -axfl if you are curious]. This will take just over three
minutes depending on the speed of your system. What is going on is
that dd is creating an image of your boot floppy in you default
directory with the file name cohboot. When it finishes, remove the mwc
original floppy, and insert a blank disk.
(1) Next run the following shell program:
echo "/etc/fdformat -v /dev/fha0"
/etc/fdformat -v /dev/fha0
echo "/etc/badscan -o proto /dev/fha0 2400"
/etc/badscan -o proto /dev/fha0 2400
Run it in the background if you wish; it takes time. The echo
lines simply display each command line just before it is carried
out to tell you what is going on. The second and fourth lines
format the floppy and check for bad blocks, respectively. In
addition, a file (proto) is being built in your default
subdirectory. This file will contain a list of the bad blocks:
look for a line with %b in it. Probably it is best to use only a
floppy with NO bad blocks: so try until you find one.
(2) make sure you have a subdirectory /f0 on your hard disk;
if not, use mkdir /f0.
(3) Next run the following shell program:
echo "/etc/mkfs /dev/fha0 proto"
/etc/mkfs /dev/fha0 proto
echo "cp /conf/boot.fha /dev/fha0"
cp /conf/boot.fha /dev/fha0
echo "dd if=cohboot of=/dev/fha0 count=80 bs=30b"
dd if=cohboot of=/dev/fha0 count=80 bs=30b
echo "/etc/mount /dev/fha0 /f0"
/etc/mount /dev/fha0 /f0
echo "cd /f0 "
cd /f0
echo " DONE but f0 still mounted !"
The second line produces the file system on the floppy using the
information from file proto. The fourth line copies boot.fha to
the floppy. The sixth line transfers the image of your system
boot floppy to your newly formatted disk (note all these things
take time). Finally, the floppy is mounted so that while you have
booted from the hard disk and have root permissions you can write
to the floppy. The last line simply rings the bell and tells you
it is done.
(4) next (noting that your default directory is /f0, i.e. the
floppy disk) enter:
mv begin autoboot
then enter
db coherent
then enter
ronflag
the response is
ronflag=001
then enter
.=0
then a response appears
ronflag=000
then enter
:q
and you should get back your prompt.
(5) Finally while the floppy is still mounted, cp over your most
useful programs to the appropriate directories (e.g., vi or
me, du, df ...) Lastly umount f0, shutdown, sync and boot your
writable floppy.
MASTER BOOT REINSTALLATION:
From: doug@mwc.com (Doug Peterson)
I want to upgrade the DOS partition from MS-DOS 3.3 to 5.0, and the
installation program refuses to work with the Coherent master bootstrap
program. It no longer asks for the ability to boot Coherent!
The problem specifically is caused be Microsoft's faulty update install
procedure. They assume you have no other operating system on the
computer.
When the 5.0 update install is run, the procedure archives the original
master boot block of the hard drive and rewrites a brand new one.
Problem is, it takes Coherent's master boot along with it. To restore
the master boot is very simple:
Use dos 5.0 fdisk to change the active partition to COHERENT. Reboot.
Use COHERENT's fdisk utility with the -b option to rewrite a new master
boot. Specifically; fdisk -b /conf/mboot /dev/at0x <ENTER>
Once completed, you can now boot either system no matter which one is
active or inactive.
LINE PRINTER HELP: From: dave@uvm-gen!pete (Dave Peterson)
I have my printer hooked up to lpt1 and cannot get any output. I have
checked my files, but, no luck. What's the problem?
1) ls -li ( The i will list the inode number, this will tell you where
you have linked /dev/lp to. )
2) ln -f /dev/lpt2 /dev/lp ( link to lpt2 IBM and MWC number the ports
differently thus lpt2 is the first printer )
[ you need to be root or bin to do the link ]
This is a partial listing of my /dev directory note the first number is
the inode number. I have linked lp to lpt2.
174 c-w--w--w- 2 bin bin 3 1 Mon Nov 25 17:36 /dev/lp
101 c-w--w--w- 1 bin bin 3 0 Fri Apr 27 1990 /dev/lpt1
174 c-w--w--w- 2 bin bin 3 1 Mon Nov 25 17:36 /dev/lpt2
173 c-w--w--w- 1 bin bin 3 2 Fri Apr 27 1990 /dev/lpt3
As a final point when you send data to /dev/lpt2 use pipes not redirection.
Try cat (file) | /dev/lpt2 it works for me.
MOVING DATA FROM A SUN TO COHERENT:
(From: PINEAU@uqac.uquebec.ca (Louis Pineau))
First, the floppy have to be formatted whether on the sun or on
the Coherent system (with fdformat /dev/rfd0c on the sun). Once
the floppy is formatted, there is no need to reformat or mkfs it
for the life of the floppy or until something unusual happens.
To write and read the floppy, on both system (sun and coherent), I
use the command "ustar" since it can handle multi-volume files
(files that are too large to fit on a single floppy).
Thus, on the sun, I do:
/usr/5bin/ustar -cvf /dev/rfd0c file [files ...] to write on the floppy
/usr/5bin/ustar -tvf /dev/rfd0c to list the floppy
/usr/5bin/ustar -xvf /dev/rfd0c [file ...] to read the floppy
On my coherent system, I use the same commands without the
/usr/5bin prefix and with the proper floppy device (/dev/fva1 on
my system).
I know that there is a way to read or write ms-dos formatted
floppy but in order to mount or unmount the floppy, you must
become superuser.
MULTI-VOLUME ARCHIVE: (From: jr@connie.de.convex.com (Joachim Riedel))
I'm trying to archive a 5 mb file (which is itself a compressed
cpio file) from hard disk onto floppy disk (fva1). I've tried cpio
and tar and even pax directly but cannot get past one volume.
Use the raw device (i.e. /dev/rfva1 ) instead of the device fva1.
SCSI MKFS NOTES: Answer From: stephen@mwc.com (Stephen Davis)
I am trying to add a second scsi drive to my system. mkfs will
not accept a proto file. What do I do?
You do not badscan a SCSI drive. Instead of giving mkfs a proto
file, you give it the total number of blocks in the partition. The
number of blocks is listed in the partition table under f-disk.
DOS TO COHERENT:
Q: The question is, is it possible to read DOS-format 360KB-diskettes?
A: yes it is :-) From: lvds@tfpbbs.uucp (Laurent Cas)
Here is the device type reference table:
Device name Sectors/track Heads Sectors Bytes Format
/dev/f9a0 9 2 720 360 KB 5.25"
/dev/fqa0 9 2 1440 720 KB 3.5"
/dev/fha0 15 2 2400 1.2 MB 5.25"
/dev/fva0 18 2 2880 1.44 MB 3.5"
If your 360KB drive is 'A:' (MSDOS reference) you can do dos t
/dev/f9a0 to list your disk, or if your 360KB is 'B:' you will
have to do dos t /dev/f9a1
drive A is number 0 and drive B is number 1 ; same for partitions
on your hard disk...
Cheers, Laurent.
UUINSTALL BUG HELP: (From norm@mwc.com)
Using Coherent 3.2, I run UUINSTALL, upon exiting, I am back at my
prompt, but, the system hangs. the only way to restart via a
reboot. Is this problem specific to 3.2 or is it something I have
possibly done?
This is a bug in the 3.2.0 release of uuinstall. Occasionally,
upon exiting, it leaves your terminal in "raw" mode. The Errata
sheet which is included with 3.2 releases mentions this, as far as
I know. To fix your terminal after exiting uuinstall, enter the
following (note that <ctrl-J> is the control key plus the letter
J):
<ctrl-J> stty sane <ctrl-J>
XWINDOWS: (From doug@mwc:)
From time to time, we get people asking about X windows on
Coherent. Many new entrants into the field of UNIX have probably
heard of the popular UNIX graphics interface called X-WINDOWS.
X-WINDOWS was developed by MIT. To the best of our knowledge they
still hold the rights to the source code and it is in the public
domain.
To the best of our knowledge, the source code takes up 110mb of
disk space! The binaries, an additional 12 - 20mb's of disk
space. It requires TCP or Streams support, neither of which is in
COHERENT.
X-windows it seems, has become somewhat of a popular GUI for UNIX
in a very short time. Various hardware firms have developed and
are marketing X-workstations, servers and cards.
On page 14 of the November 1991 issue of UNIX REVIEW, is an ad for
X11 Release 5 for System V/386. The price advertised is $495 with
printed manuals, $395 without. So, X is not cheap via the
commercial route.
Given COHERENT 3.2's small model compiler, it is obviously
impossible at this time for COHERENT to even compile the code, let
alone run it.
Tar Help:
The Coherent version of tar has been known to create problems for
users. It is believed that the latest version of tar has
alleviated most of these problems. Some of the original problems
include inability to read a tar archive to tar creating recursive
inode/file loops that can only be removed by "clri". The more
recent Coherent releases also includes ustar, which appears to be
much more robust. It has been suggested to use the ustar command
instead of the Coherent native tar command in most cases.
Setting Boot Partition: DOS or Coherent?
Occasionally, a user may want to boot to Coherent for the most
part, rather than come up in DOS by default. You can leave the
DOS partition in tact, and switch between the preferred operating
systems on as "as needed" basis. To do this, simply use the fdisk
program in either operating system and make the partition active
for the operating system that resides there. Reboot the system,
(AMI Bios system owners require a hard reset) and the system will
now boot to the partition made active with fdisk. For example, if
you wish to boot DOS by default, make the first partition active.
If you want to boot Coherent by default, make the partition active
that Coherent resides on.

Creating a Bootable Floppy for Emergency Use:
Help With Installation: From: Bob Hemedinger <support@mwc.com>
-----------------------
1) I'm updating from version 3.x to 4.x and am being asked for
a serial number from a registration card. I don't have one.
- updating users do not need new serial numbers. Use
the number supplied with your 3.x version. If you don't
know what it is, read the file /etc/serialno.
2) I'm seeing various characters in the upper right hand corner of
my screen when Coherent boots.
- These are used by MWC for debugging some installation
problems. If installation fails to boot, the last character(s)
displayed in the corner of the screen will give a significant
clue as to where the failure occurred.
3) I get a core dump during the installation. The last digits of the
eip register are 2EF.
- Call MWC for a new set of installation diskettes.
4) I see a prepare_gift() message when Coherent boots.
- The tertiary boot program, /tboot, is attempting to read your
CMOS to get your hard drive parameters and other information.
This process met with an unexpected error, usually related to
the initialization of cache memory. If Coherent continues to boot
and run, ignore the message. If the boot fails, try this:
- hit <space> when prompted by tboot to abort the
boot process. Type 'info' at the first '?' prompt.
Ignore the returned data. At the next '?' prompt,
type 'update' or 'begin' if updating or installing,
or enter the name of the kernel to boot. Follow
this procedure exactly. Do NOT try the 'info' command
more than once.
5) When booting the installation, I come to a # prompt with a message
displayed that I didn't boot properly and need to reboot.
- tboot failed to pass what you typed at the '?' prompt
to the installation program. A prepare_gift() message
was probably displayed before this, sometimes too quickly
to be seen unless one is looking for it specifically.
One can either reboot and use the procedure from item #4
(above), or type 'build' at the # prompt to install, or
type 'build -u' at the # prompt to update from 3.x.
6) During boot, I see a message about not being able to brelease a
modified buffer.
- In most cases, Coherent will continue to boot normally. In some,
the message will scroll endlessly. This is an indication of an
incompatible bios and is a very rare case. The Epson bios set
has sometimes produced this problem. If at all possible, update
the bios chips in the computer. Phoenix is the bios chipset
MWC recommends.
7) After installing disk #1, I reboot Coherent from the hard drive, but
am never prompted to enter a diskette -or-, I reboot Coherent from the
hard drive, and the system hangs with a Coherent banner message on the
screen.
- Thou hast most likely chosen to use either virtual consoles,
or no virtual consoles but did select a loadable keyboard
table. Coherent is hanging at the point where keyboard
initialization
takes place, indicating that the keyboard does not properly support
IBM scan code 3. This is a different keyboard mode than DOS
uses, and probably a good 10% of keyboards of Asian origin will
have problems with this. Reinstallation without virtual consoles
nor loadable keyboard tables should resolve this.
8) All diskettes install without a hitch, but after rebooting, fsck finds
all sorts of DUP blocks and bad i-nodes.
- This is rare, but is usually the result of installing onto a
large partition. This is possibly related to sector translation
firmware and/or the manner in which the firmware deals with
bad blocks... we don't know yet. Break the large partition into
smaller partitions and try installation again. If this is an ESDI
drive, and the controller is doing sector translation, try switching
it to native mode.
4.0 Binary compatability with other software:
--------------------------------------------
Coherent 4.x compiles and runs COFF executables. Third party COFF software
will most likely run if the following conditions are true:
- does NOT use shared memory nor shared libraries. We plan to
implement these in the next release of Coherent. Coherent
4.0 shared memory is not System V compliant.
- does NOT rely on sockets nor streams. Again, we plan to have
have at least one of these in the next release.
- does NOT use graphics. Coherent 4.0 is strictly a text-based
system. Again, we plan to have some form of graphics support
in the future.
Some examples of 3rd party software running under Coherent 4.x:
ACUCOBOL
Xtree
BASIS International BBX/Progression 3 (BASIC)
FilePro
- For more info, please contact MWC, or email sales@mwc.com.
Compiling programs:
-------------------
1) The compiler is complaining about not enough memory.
- You may have a significant amount of memory, say 2 or 4 Megabytes,
but one must also account for other running processes. The compiler
by default tries to do all of its work in core (memory). If it
aborts due to not enough memory, then add a -T0 to your cc command
line. This will force the compiler to use temporary files on
the hard drive, rather than in core.
2) I'm trying to port software from a bbs or the net. Is Coherent closer to
System V or BSD?
- You should select System V wherever possible. We tend to
avoid BSDisms.
3) When compiling a package, the linker complains that getwd() doesn't
exist. This worked under 3.x. What happened?
- With Coherent 4.0, we have gone to getcwd() in place of
getwd(). We have supplied _getwd() for people that need
getwd(), but we are planning on dropping this in the
future.
Help with serial ports and terminals:
-------------------------------------
d10590@tanus.oz.au (Robert Chalmers) Coherent V4.0/4.01.
Thanks, Robert!
If you follow the installation instructions, and choose their defaults,
you will end up with a ttys file very similar to the following.
0lPcom1l <--|
0lPcom2l | -- The four standard COM1, COM2,
0lPcom3l | COM3 & COM4 ports. NOT CONFIGURED.
0lPcom4l <--| See the notes below for configuration.
1lPmono0 <--|
1lPmono1 | -- The terminal virtual consoles.
1lPmono2 | These REPLACE the V3.x's 1Pconsole
1lPmono3 <--| entry in that versions ttys file.
You dont have to touch these.
For example, on my system I have the following hardware. One
standard HDD/FDD Controller (IDE) with COM1, COM2 and LPT1 on board,
and enabled. These live at 3F8 - IRQ4, and 2F8 - IRQ3. LPT1 uses 378
and IRQ7.
One standard Taiwan Multi I/O card with 2 COM ports, one printer
port, and one game port. This card can be configured as COM1/2 or
COM3/4, and LPT1 or LPT2. I have the jumpers set for the following.
COM3 at 3E8 - IRQ4 and COM4 at 2E8 - IRQ3, with the second printer,
LPT2 at 278 - IRQ5.
Now, setting them up, as applied to this type of 2 board setup. If
you are not sure if your installation configured the ports
correctly, then follow the instructions in the Release Notes and
Installation Guide under 'Asy' exactly as they appear, regarding the
making of the devices. Dont change anything. yet. Now, the thing
to note is the rule on IRQs and Polling. If you are using COM2 as
your modem port, (seems to be the most used option), and COM1 as a
terminal connection, and both are using IRQs, then the other two
must be Polled. COM3 and COM4 must be Polled. Observe my settings
listed,
0lPcom1l <--- Serial terminal on COM1. IRQ4
1rLcom2r <--- Modem, incoming, on COM2. IRQ3
0lLcom2l <--- Modem, outgoing (the same modem) on COM2. IRQ3
0lPcom3pl <--- Serial terminal on COM3. Polled
0lPcom4pl <--- Serial terminal on COM4. Polled
1lPmono0 <-|
1lPmono1 |
1lPmono2 | --virtual screens.
1lPmono3 <-|
The Serial terminals are shown as 'disabled' in the above listing,
but when they are connected, you simply type 'enable com3pl' and
presto!, you get a login prompt on that terminal.
In SUMMARY:
Install with all defaults.
Run the three configuration commands in the Asy entry.
The asyxxx entries in your /dev directory are the prototypes for
the comxx devices, so you can ignore them for the purposes of this.
Decide which lines you will use, and check your IRQ/Poll combination.
Check your physical wiring.
For terminals, you only need three wires:
D25 connectors. TXD to RXD, RXD to TXD, Common Ground.
2 --> 3
3 <-- 2
7 <-> 7
D9 connector. TXD to RXD, RXD to TXD, Common Ground.
2 --> 3
3 <-- 2
5 <-> 5
In the above setting, to call out on the modem, you MUST type
'disable com2r' before you can call out on com2l. When you are
finished, type 'enable com2r' to put your modem back on line.
Other things of note: Old Xt's with a com port and any version of
TELIX/PROCOMM/etc etc make good cheap terminals, as do old terminals
that businesses throw away as obsolete.
Windows 3.1's Terminal will emulate a vt100. If you have a second PC
connected to a Coherent serial port, its 'almost!' like having Xterm
running Coherent in a Term window. You can even cut and paste
between Word for Windows etc and vi. So who needs X I ask?
