Of course, if you have a UPS running your machine, just pull the plug
on the ups until it shuts your machine down and do not plug it in
until you want it on again.
But even if you do not have a UPS, you could run genpowerd or
something. The interface is to a serial port, and the interface is
quite trivial. You can look here:
http://www.ibiblio.org/mdw/HOWTO/UPS-HOWTO.html for details.

You want to save a record of the session?
See script(1) man page.
script can be run from from a shell script.

Hmmm... how about connecting a mouse to the serial port, then write a
short program to invoke the shutdown command when you hit a mouse button?
If the PC has some auto-shutoff functionality, you won't even have to use
the power switch afterwards.
Alternatively - have you considered just using the power switch? As far as
I know, the only problem with shutting down the PC this way is that the
filesystems won't be synchronized, so you might loose data. But you're
only using the system as a router, in other words, stuff is loaded from
the hard drive at startup and nothing much happens afterwards. So there
won't be critical data you might loose, except maybe parts of a log file
now and then.
Also, using the PC as a router won't need much ressources. I heard of a
project called "linux router project" that fits all the needed software on
a single floppy disk. You wouldn't even need a hard disk. In the unlikely
event that something happens to your floppy disk, just make a new one from
a floppy image.

See the man page for gpm, under "Special commands". However, the
default behavior requires a semi-complex sequence of mouse clicks.
Fiddling with that would require recompiling gpm--easier than soldering,
no?

Thanks, maybe "script" hardcoded inside a script *would* work assuming
something like this?:
script mylog <<-_end_of_here_doc
less mylongfile
: place entire remaining script inside this here doc
_end_of_here_doc
In any case, "script" has not yet been ported to Redhat's Cygwin tools
for WNT yet; I would like a soln for both UNIX and Cygwin.
I'm aware of simple work arounds, I just thought it would be
*fun* if one could somehow inform less of the terminal window
size so it *would* page properly when it was inside a block
that had it's STDOUT/STDERR tee'd to a file. I thought there
might be a way to do this by saving the STDOUT file handle
"above" the block and then have less re-use that saved
file handle / descriptor- but I'm over my head.. ;->
Again, I just thought this might be a fun problem to solve,
it's not a serious problem.
thanks again,
Tom

You have to find other way to initilaze terminal for your app.
Look into manpage for open(1) command. It is what you need.

I gather since you mention SuSE that you are using apsfilter? Have you
checked out the /etc/apsfilterrc and the /etc/apsfilter.* (for your
printer)? There are very configuration options in both these files. I
would also take a look at the SuSE support database off of www.suse.com for
any additional information on the problem you are reporting. If memory
serves, there is a lot of information on apsfilter printing there.
