[comp.dcom.lans] Need help with system configuration

warren@mdcbbs.com (10/19/90)

One of my coworkers wants information about
how best to tie just 2 PCs together.  The
idea is to purchase aone copy of an expensive
statistics pkg.  is copy would reside on a PC
upstairs.  Only the terminal upstairs or my
friend downstairs would use it at one time.  If he's
using it downstairs, it would have to be as a background
process; the upstairs PC would have to be able to be used
at the same time for other programs.  One machine is a 
386 DOS machine.  The upstairs machine is to
be purchased.  The only requirement is that it be
a 386 or better.  He is hoping to configure the new machine
to have all the features needed to accomplish the
desired results.  Is there a way to do this without
a 3rd machine networked to these 2 machines?  They
hope to use Teltone (a voice over data product which
use the pbx system and phone lines) or modems.  

Would it be possible using OS2, WIndows, Unix, or not
at all.  Any advice or informations you can give me
would be greatly appreciated.

Thanks a lot,
Connie
