Several posters have addressed means of handling PC I/O from the COM ports.
I suppose the typical application is the ability to run a PC remotely so
you can have a great CPU and lots of software in one place and continue
to run it from home. I recall a couple of such remote-operation software
packages at SIMTEL. In particular, I just tried out TeleReplica (tr3-5.zip,
which I copied from uwasa.fi) and found that it handled perfectly everything
I had hoped (though I know it doesn't handle graphics output).

HOWEVER, I am still in the market for software which accomplishes the same
thing on the PC end, but allows the user to sit in front of a UNIX box.
I've got some PC-specific software to run and a number of users who
connect to our SUN workstations. Everything is connected (or could be) using
modem lines and also using ethernet links. Surely someone has a way to
work this out. I would be delighted to see, say,
	a) A UNIX telereplica client, or
	b) a DOS rlogin server
I recognize that there are unavoidable limitations (e.g. DOS software which
handles screen I/O with direct memory writes is not going to work), and
I know that the UNIX routines are going to somehow have to make sense of
DOS output like INT21 functions to write anywhere on the screen. But for
a program with relatively simple I/O, it would seem natural enough for
someone to have workd out the necessary software ...

Oh, a DOS emulation window exists but isn't really enough since the PC
has some plug-in cards and device drivers which I suspect can't be
duplicated in the UNIX operation of the CPU.

Follow-ups are fine, but I suspect there are a lot of specifics to my
request that might be best addressed in email exchanges with knowledgeable
sources.
