Hello,

I have a big problem with a multiserial 8 ports card.

I have to build up a linux system that act as gateway between modems and
tcp/ip. I have a multiserial card but ... look at the problem:

I have the card ... and nothing else. No manuals, no dip switch configs
no informations.

There is only a model name printed on the card.
This logo and mod. name is:

***
*** TECH SI4-A
***

I would like to know who is the producer of this board and/or where can I
find its tecnical manuals and/or programming infos about the card.

The layout of the card is more or less (i'm not a good ascii artist):

(*) Four UMC chips: UM82450
(**) The card is made by two pieces, one on the top of the other.

If someone of you have any kind of information about this card, please let me
know. I need it!!

Thank you in advance.

The installation of MapleV R3 for Linux went smootly yesterday.

It comes on 17 3.5" disks, as a split cpio archive. The whole package
needs 20 megs of disk space. Any good Linux hacker short on space could
figure out in a few hours how to persuade cpio to leave out the share
directory and, maybe, even the X11 stuff. The library itself is over 10 megs.
So this is a full *nix release indeed.

Up to now, i have been running Maple from the console and found it very
familiar, much like the 1989 version on an Apollo workstation or
the DOS version i use daily. No surprise is good surprise. The most welcome
feature is the command line interface (readline like) which i know so well.
The "license manager" consists of a world writable directory with a copy
of information given on the first run, and a log of usage. This is what i see:

omicron:~/maple$ uname -a
              Linux omicron 1.1.51 #1 Sun Sep 18 13:59:48 CDT 1994 i486

Maple R3 for Linux is on a secure NFS mounted external disk,

Of course that's correct if you are looking for *text editor*
(like your jed). I thought the thread is on *word processor*, no ?
Beside there is NO WYSIWYG *wordprocessor* for text-only terminal,
since by definition it won't do WYSIWYG.

Of course there are zillions of text editors...

I found that with one of our NNTP servers there was a problem with
the message size sent by xvnews. I patched the source to be a bit
more gentle, and all works fine now. Note that the later versions of
xvnews (2.2, patch 1 or newer) allow sorting on subject which also
provides quite a reasonable way of threading messages.

Let me know if you need the patched source.

This is an ongoing debate.  If a text editor + LaTeX is a
viable alternative to a standard word processor like MS Word in
an office environment, then there needs to be some way to share
documents with other platforms.  We use RTF to share between
Mac/Windows.  If software for Linux can't do this, then it
should be able to read it plain text and translate the 
"lf" characters.  In the case of a Mac, this is ^M.

MS Word can search and replace the unix "lf" character so that
text files written on a Linux machine can be displayed on a 
Mac or Windows machine.  

I think it can be acceptable to translate a formatted document on
one platform to plain text to be formatted on another platform.
However, thus far, I have been unable to get a Linux text editor like
emacs to do a search and replace of the ^M lf character.  

Looking at what I have written thus far, I noticed that I have
gone off the subject of this thread.  Sorry about that.  Seeing
this discussion kind of made me remember my own efforts in trying
to use a Linux machine to produce nicely formatted text in a
cross-platform environment.  Actually, if anyone has advice, I 
would appreciate it.  Feel free to send me e-mail.

I think wine has it's own newsgroup (comp.sys.emulators.wine ?) so there
dosen't seem much point in including it under the comp.os.linux.*
heirarchy as I don't think there will be enough Linux specific
material to warrant it here.

As for the rest, how about comp.os.linux.emulators ?

I think that comp.os.linux.video would be a good step forward, as it
was by far the most difficult part for me when I first installed.

gcc produces diabolically bad ARM code prior to 2.6.x which will allegedly
cure this. The arm has a bizarre and 'truely risc' architecture with each
instruction having a condition code (normally set to 'always') but can be
things like NE, EQ etc. Thus you can do some neat optimisations avoiding
jumps breaking pipelines if your compiler is smart.

When a non-root user tries to change a password, they get a "can't open /etc/

   Linux automatically blanks the screen.  Your monitor evidently picks
   up on this and goes into powersaving mode.

   `setterm -blank 15' will set your monitor for a 15 minute period
   instead of a 10 minute one.

That's only true while NOT running X. Linux console driver blanks my
screen correctly while displaying a console screen. But with X on
display the X-screensaver determines blanking behaviour and not the
console driver!

   Who knows?

   You're being silly. now.  Please read the manual page for `setterm'.

*flame on*
And please read all prime XFree manual pages before flaming someone else!
*flame off*

   However, it might be considered odd that your monitor goes into
   powersaving mode for 16 bit and not 8 bit modes.

   Please don't post a hysterical warning unless you're sure.  Better
   yet, never post a hysterical warning -- it is is true, people can get
   hysterical without too much help.

I'm *sure*!

Well, what's better: posting warnings or the possibility of blowing
several monitors?

I'm pretty sure Slackware 2.0 is 1.0.9.  (Me: 1.1.50 at home, 1.1.52
