DEC's DSP5400 will work on the 3230, as well as the 6280, but I will
not recommend it, as it is very loud and not very fast compared to
the little 1GB drives.

I did not have evaluated other 2GB drives till now. Another solution
would be to use two 3 1/2" 1GB drives, and stripe them (as long as
you have enough free SCSI Id's).

Sincerely,
Klaus Steinberger

Hello,

I have need of information concerning the use of the escape key on a unisys
uvt1224 terminal while connected to a unix box by modem.  

One of my contingency has a unisys uvt1224 at home, and says that, whenever
he calls in over a Microcom 9600 baud modem, his escape key "emits a sequence of 
characters which include '~' and tends to capitalize letters" on him.  This,
of course, makes working with vi a real bear.

Does anyone know anything about this and a solution for it?

Please mail me at the address you see below, or just send the info to this
newsgroup.

Thanks a bunch.

There are two software products for the 2200 which should be sufficient to 
accomplish what you want to do.  They are SX1100 and NFS 2200 (which is a 
subset of SX1100.)  SX1100 is a version of AT&T Unix V.3.1 for the 2200 series.
It contains significant networking capabilities such as ftp, NFS, uucp via
Ethernet using either a Host Lan Controller (HLC) or DCP Ethernet line 
modules, etc.  With SX you should be able to configure a print queue that
would ship the file to SX and execute an lp command there.  (Unfortunately
SX does not have the Berkley lpr/lpd commands.)  This is discussed in the
SX Administrator's Guide (7831 1016-000) pp 10-30.  We use it here to go the 
reverse direction for small print jobs that we want printed on a Postscript
or HP laser printer.  

A cheaper alternative would be NFS 2200 which, as I mentioned above, is a 
subset of SX 1100 - not all commands are included in the release.  There is
enough to do your task though.  You could move the print files to the 
2200 via NFS or ftp and have a cron job that looked for something to 
print every few minutes.  Hope this helps.

Sure X windows will run. There is the PGE product from UNISYS, or
I guess you could go some other route there.

The system is essentially an EISA PC (33 or 66MHz i486).

Currently the PS/2 mouse port driver is not supported, use a serial
mouse on COM1. Release 1.1.2 will introduce PS/2 mouse support.

Don't forget to use the ECU / SCU to add your video board. Note, the
EISA config file !VCW6000.CFG should cover well enough for most VGA
or SVGA controllers.

We use C++ here at ACUS on U6000. It is just a port of AT&T's compiler.
Of course if you are considering using C++, you should also read my
C++ critique. There are far better object-oriented languages out there.

Hi Charles - Long time no speak!  Re printing to 2200/xxx line printers from
a Sun network... Do you have a connection (directly or indirectly) from your
2200 to the Sun network?  If you've got a U6000 in the mix, this is a pretty
simple thing to solve.  If not, it's still solvable, but not as pretty.  Here
we go with some examples I've implemented at other places during my life as a 
Unisys and unix hack:

1. U6000 solution: Put a U6000 in connection to your 2200 network.  Use either
   Ethernet or comm DCA, doesn't matter.  Software required in U6000 is IS6000
   and software required in 2200 is DDP-FJT (because DDP-PPC is now part of 
   the base O/S per last USE conference Q&A).  Then implement a print queue in
   the Sun boxes that fires a shell that actually copies the printfile from 
   the Sun box to the U6000 box, and then remote shells into the ISSPOOL
   program (part of IS6000).  Use of this method keeps you from having to run
   both DDPFJT and DDPPS as background runs in the 2200; you only need the
   DDPFJT stuff (use of DDPPS would mean using ISSYM instead of ISSPOOL, else
   the scenario remains the same).  I've got this in a client's shop that is
   HW:Solborne/Sun/Dell/Pyramid, SW:SunOS/SVR4, and they love it - nobody
   prints large stuff on the Unix side anymore, it's all line print output
   now.  Down side of this is that the darned S/W is *expensive*, and that
   you need a *U6000* box in the mix.  If you've got a SPO, however, you've
   already got both Unix parts, so it's a no-cost solution other than the
   darned host software.

2. Non-U6000 Case: Still need connection to the 2200 somehow.  With a LAN
   connection and DDN2200, you can set up the Sun queues to fire an FTP up
   and slap the printfile into the 2200 using a unique filename pattern.
   Then you slap together a small background run that scans for files of
   that pattern, and enqueues the files into their patterns' associated
   2200 print queues.  This is not a cheap solution, however, because the
   software is *still expensive*.  You might be able to pull this off with
   one of the UPLI packages, the TCP/IP 1100 FTP service which is buried in
   the last UOM Distribution Tape.  This would require a BTI box, which is
   the same thing as an HLC (made by Bus Tech Indistries, same folks that make
   the original HLC for unisys and the CPA for STK) but costs a lot less, and
   a BMX connection to hang it on.

Anyway, this is just a couple of ideas.  There are others (e.g. PCPRINT and
smart printers and the like), but all of this just supports my read of the
Open Systems thrust that Unisys and so many others are embarked on these
days:  THE PROBLEM IS NOT FINDING A SOLUTION, OR THE MYTHICAL RIGHT SOLUTION,
BUT JUST PICKING ONE OF THE POSSIBLE SOLUTIONS AND THEN MAKING IT STICK.

Gee, sounds like I'm gonna be doing this for a while!

Cheers, Walt.

I am trying to do some protected mode programming using the 286/386
instruction set. My final goal is making a simple operating system with
preemptive multitasking capability.  


I am looking for some example assembly programs, probably in MASM or TASM
syntax, for the 286/386 protected mode. An ideal example program would be
switching into Protected Mode form Dos, run several processes preemptively
and exit to Dos. I know some of you guys are really great and have written
a complete O/S for the 286/386. I really don't mind seeing those codes. 


Also, I am using TASM to compile my code. I am not sure if this is an
ideal tool for the purpose of developing an O/S. Do you have any
suggestion for an appropriate set of development tools? Is the Intel
Development Toolkit good?


If you have any suggestion for any further information, please mail it to
me. I am just a beginner to O/S programming but I would love to share
other people's experience. Your responds can be mailed to

In a context switch you are probably using an interrupt, either hardware or
software (if you aren't then you're in trouble), and interrupts store the
flags,
CS and IP in the stack _before_ jumping to the new location. If you need the
old values then get them out of the stack.
