I found a driver on the multitech site that would force my modem to
operate under com3 or com4 instead of com5. When I checked my
settings under windows 98 the modem shows up as a COM4 device but when I
run MS MSD.EXE from dos mode it shows no devices for com4 (see my print
out of win98 settings bellow) I've included all my Linux settings if
anyone has any ideas.
Thanks! ;-)

I have a Ditto Max. It runs off of a floppy accelerator card. Works
great with Windows (but see NOTE below). I have not been able to get it
to work with Linux.
According to the ftape documentation it is supposed to work, but I have
my doubts. I have posted several comments and questions about this but
no one has ever responded saying they can make it work.
In my case I *can* get it to *almost* work but there are two problems:
1. It only reads/writes at about 1/2 MB per min. In Windows the drive
does 18MB/min -- more with compression.
2. I get permanent read errors. I have been able to read back up to
about 10 MB before getting errors, but never more. The same tapes work
error free with Windows.
NOTE: Getting the tape to work with Windows NT took me several *months*
of phone calls to Iomega support. Turns out that what they shipped
simply did not work in NT. I got the run-around until they developed and
shipped both a new accelerator card and some new software. To their
credit, they did supply me with both free of charge, but it was a
frustrating several months. Then, just 1 month short of the warantee
period the drive went belly-up. Again, Iomega replaced it for free but
this was still a pain.
If I were to do it all again -- and I think I will need to to get a tape
that works with Linux -- I would get a SCSI tape. The money saved (a
couple of hundred bucks) by buying from Iomega was not worth the
hassle.

Subject: libc5->glibc utmp problem
Date: 6 Feb 1999 22:59:08 GMT
I updated my system to glibc (2.0.6) from libc5. I recompiled practically
everything to use the new libc. I made very sure that I updated all the utmp
manipulating programs. The system runs just fine, but there is a strange
problem concerning utmp entries. When an user logs out from a tty (ttyXx in
which X is pqrs and x is 0-f) the user gets logged out but his/her utmp
entry is not removed correctly. Uptime and who (sh-utils-1.16) say the user is
still in, w (procps-1.2.9) says (s)he's not. The tty is freed correctly though
because another user can login on the tty later. The problem occurs with all
kinds of connections. If the screen program is used to allocate the tty, the
utmp entry will be removed correctly during logout (when a screen session is
ended).
Actually I have two systems with the same problem. Another one is running
Linux/m68k and glibc-2.0.6, another one is running Linux on an i586 and has
glibc-2.0.7pre6. Both systems are alike - I've compiled everything myself
and they remind each other very much.
What is causing this problem? I really would appreciate your help - the systems
run fine but the problem irritates me as I don't know what's causing it.
Here is an example of this problem. These clips were taken after a clean boot:
vesuri:~> w

root tty2 10:12pm 2.00s 0.82s 0.15s pico -w
I've logged in as root on tty1 and tty2. This is normal. Now I telnet to
localhost just to demonstrate - there would be no significant difference using
SSH or so. I login to allocate ttyp1 so that there are 3 users logged in.
vesuri:~> telnet localhost

Okay, still normal. Let's log out.
vesuri:~> exit

Now I'm root again. There should be 2 users logged in (like there is).

3 users still logged in according to the uptime header but only two of them
are shown in the w output. What does who say?
vesuri:~> who

No, since this is *very* OS and hardware specific and you might have
a terminal / keyboard with no Num Lock at all for instance (and in
addition *you are not to mess around with my NUM LOCK*; get your own

Cannot say wether it works with all, but mt -f <tape> offline might
do the job (it does for my SONY and did it for a HP too).

Probably you should use sed; something along the lines of "s/\n/\n\r/"
should do fine.

I installed the new timidity and it still plays too fast.
You have to take this into account
1-Even with the old timidity kmidi still played correctly
2-The problem is only present with the plugin ump. The beta I've tried of ump
flushes netscape and I can no longer run netscape until I remove it and put
the other one back.
3-I have never played playmidi so I wouldn't know if it failed before
4-The bug is indeed with the kernel, kde seems to be the only one able to deal with it.

A serial console is a classic terminal - something like a DEC VT100 or
a Wyse terminal, maybe even an ASR-33 typewriter.
Back in the old days, every console was a serial console. And when you
were out of luck, problems with the serial line could garble the

I thought about this, and haven't come up with a *complete* answer,
but there should be a way that a guru could find.
Here is a partial answer, hope that you aren't too experienced with
UNIX or you may find this pedantic.
to run a task in the background end the command line with an &
for example:
ls -laR &
the stdout is now still to the terminal that started the process,
so you will see tons of stuff scrolling by even though you can still
type new commands and their output would be put on at the end of the
output buffer.
to redirect that output to a file and run in the background:
ls -laR > list-o-files &
stderr is still to your terminal. to redirect both stdout and stderr
to the file and run in the background:
ls -laR > list-o-files 2>&1 &
to run a job in the background and have it trap all HUP signals
(this is the signal that child processes receive when the parent
process exits) so that when you exit your shell or disconnect the
telnet session it stays running in the background:
nohup <cmd-name> <args> &
to run a process and then "suspend it" (cause it to pause and
return you to a command prompt) type <ctrl-z> (In bash anyway)
Then you can type "bg" to have that suspended job run in the background.
To bring the job forward you can type "fg" and then it will be in the
foreground again.
The following might work for some processes, but not all processes
(depending on how the "interactive" part was handled. some processes
will complain if their stdin is disconnected, other processes
don't care)
nohup passwd | tee -i &
*this runs the password (interactive) process while trapping the
hangup signals and placing it in the background, it also pipes the
output to the "tee" command wich copies the standard out of the password
command that nohup is redirecting to "nohup.out" and redirects
it to standard out as well. The -i option to the "tee" command
tells it to ignore signals received (except of course SIGKILL (9))
*to bring the process to the forground type "fg"
* to tell the process to go back to the background type "bg"
* to check on it's output cat the "nohup.out" file.
If you disconnect it should still run, but when you reconnect I
don't know how to go back to it's interractive input?
Like I said this will only work with some processes depending on
how they handle their pipes. If they detect the closed stdin pipe and
exit....
You could write an "expect" wrapper that could handle this, but it
would require a little programming know how.
If you really know what your doing (you wouldn't have read this far
anyway. ;P ) you could write a "wrapper" program in an efficient
compiled language that did these type's of things with any
interactive program. Sounds like "screens" does this.

If you mean ordering a directory listing by size and extension then
unless I am mistaken you can only do this in one directory at a
time. With find you can search recursively all subdirectories.
The point is that with a gui tool you are limited to what you
can see; on the command line you aren't. The command
is
find . -size +50k -name "*.jpg" | xargs cp destination
