	There is a reason unix doesn't send some escape sequence out and see
what comes back.  That is because different terminals use different escape
sequences for the command to return the terminal type.  Other terminals don't
have such a command.  Escape sequences for some terminals lock up other
terminals.  Its really frustrating to the user to lock up their Banna-10
terminal while checking to see if it responds to the ANSI escape sequence.

	Lowest common denominator. at least for the U.S., says that about the
only thing that is safe to send out before the computer knows what kind of
terminal it is talking to is, is 7-bit ascii (typically only printable and
control characters).

I had the reverse problem when I compiled a program.  It was a tiny

it and was wondering why it would do absolutely nothing.  For 3 hours.
Then I realized that there is a "/bin/test" and it was executing

	There is a program that uucico always calls to (re)enable the port when
it is done.  Unfortunately, it does this no matter whether the port was
enabled when it started or not.  The end result is that no matter the origional
status, the port is set to enabled by uucico when it done.
	I think the program is called "enable" or some such (Coherent system is
at home and I'm doing this from memory).  If you run a tight ps loop and watch
uucico cleaning up, you'll find this program name pop up in the process list
for a few seconds (that's how I found it).

	My solution was to replace it with a shell script that returns success
and does nothing else.  Kind of a crude solution, but uucico wasn't being very
elegent to begin with.  Unfortunately, this "fix" will affect *all* ports that
you run uucico on.


hope this helps,

Hmmmmm...... Verrrrrrrry strange. I've got my modem on a port that is

A recent timing of tar writing about 1 Mbyte (200 files) to /dev/fva0
gave over six minutes of wall time with no other user proceses
running.  The floppy had been formatted using the default skew and
interleave values of fdformat.  Interestingly, the format only takes a
minute or so.

Also, the man page for fdformat describes the -a option as producing
output of the form:

hd=d cyl=dd

but the actual program has this reversed:

cyl=dd hd=d

I believe that the second progress message format is correct and more
common version.

Tar actions seem to stop most system processing.  For example, while
tar is writing, I ran sync from antoher virtual console.  The sync
took several minutes to complete.  Also, a ps seems to take quite a
while if a tar is running.

Is all this the fault of a crummy IDE/floppy controller?  Does the fd
driver need a rewrite?  Should I use values other than the defaults
for skew and interleave with fdformat?

I recently decided to reinstall my system, and before doing so I 
responsibly backed up my working directory with the command:

tar cvbf 20 /usr/jims

This worked fine, as it had multiple times in the past, so I decided
to go ahead and reformat my Coherent partition during the reinstall.

After the reinstall, I decided to retrieve my work by executing:

tar xvf /dev/fha0

Which worked fine at loading my saved files until it read:

{Insert next disk or press quit to abort}

Imagine my surprise when all of my backups over the past 4 months
have required only 1 disk!  Apparently tar simply quits when it
reaches the end of the first disk (while writing) without giving
any opportunity to load a second disk.

For me, this represents about 3-400 man hours of effort lost.  
Don't let this happen to you!

Jim

P.S. I have a QIC tape on my system.  If I knew of this problem, I
could have easily backed up my work by copying to a DOS partition and
backing that to tape.

The reason you don't have job control features in any of Coherent's shells is
because Coherent doesn't yet support the signals you need to make job control
work. I haven't seen it in a while (my Coherent experience comes from a
friend's machine at work), but I think /usr/include/sys/signal.h
only has 16 signals defined it in under 4.0.1, whereas most versions of
Unix have at least 32. (And, if memory serves, Coherent 3.2.0 only had 9!)
You need SIGTSTP (sent when ^Z is typed) and SIGCONT for job control,
and Coh just doesn't have them yet. Seems to me that enhanced signal
capabilities would be needed for X11 & TCP/IP support, so I wouldn't be
surprised if MWC has 'em in the works as we speak. ;)

As for the other ksh features, well, heck, don't look at me: I'm a tcsh
fan myself. ;)

1. shutdown your system to single user mode.

3. enable "console" and disable all devices like "color0", "color1"...

: Is anyone out there getting decent hard disk IO performance under Coherent?   

On my ST-506/RLL drives I'm getting anywhere between 100K-209K of
throughput depending on the particular partition being tested.

Judging from the numbers you listed in your original post (29K-69K)
you'll probably need to do some experimenting with the "n" and "m"
values used by mkfs when it creates filesystems.  When I first
installed Coherent and mkfs created the filesystem with whatever it
uses for defaults I had the same lousy throughput as you describe.
After spending a day doing some experimenting with different values
and Iozone to provide the benchmarking I was able to get the figures I
mentioned above.

What you should do to experiment is use an idle partition if at all
possible and try different values until you start getting better
figures from Iozone.  Be sure to do a back-up though, even if working
on another partition, because it's very easy to misstype the name of a
partition and mkfs doesn't ask twice before it blows away everything.

If anyone reading this would like a nice project, how about a utility
that could figure out the optimal values for mkfs's "n" and "m"
parameters.  It would sure beat trial and error.

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.

      Unfortunately, tar is not a mult-volume archiver, and never

      to use the raw device, /dev/rfha0 to enable this feature. 

      In Coherent 4.X, tar is a link to ustar.  So in 4.0 you can use
      tar cvbf 20 /dev/rfha0 /usr/jims
      to get multiple volumes in an archive.

      tar cvbf 20 /dev/fha0 file  is the single media (tape) archiver


      I use tar cvf /dev/rfva0 directory   to do my backups.  Note 
      that I do break it into directories, that span no more than

Earlier today I called MWC and ordered the four new disk sets for
Coherent 4.0.  These are the DDK (4.0 device driver kit), the GNU
toolset, the latest Cohware (volume 3, I guess), and the GNU gcc
compiler.  All but the compiler are shipping today.  The estimated
ship date for gcc is sometime in late February.  I hope that it's
Februrary 1993 and not some other year.

Still, I'd really like to buy a commercial ANSI C compiler.  I am not
interested in a multitude of additional features or an IDE; I just
need a robust and supported ANSI C compiler.
