Firstly, sorry about the strange cross-posting of this article, but I
believe it is relavent to all. 

One of our sites has has several PCs running SCO Unix, with a mixture of 
monitor types (most are WYSE, but of differing specs), Unix termcap allowed 
everything to work fine.

The problems started when we installed a DEC Alpha running OpenVMS, we got it
talking to the Unixboxes via UCX (DECs version of TCP/IP). Unfortunately 
the software that we are running on the Alpha has been hard coded to support 
VT300 series terminals. This means that the VT terminals we have work on both 
the UNIX boxes and the Alpha, as do the higher spec WYSE terminal (these have 
a VT emulation mode), but the lower spec WYSE terminals and the PCs wont work
(the PCs running UNIX that is, we have all the DOS based PCs working fine)

The Alpha will only ever be telneted to from the Unix box, so I wonderd if it
is therfore possible on either the Alpha or the Unix boxes to 'convert' VT
escape code sequences to something that the WYSE (and PCs) support (ie ansi) 


Thanks for any assistance, and be easy on the Unix, i'm a VMS person at heart 
and my knowledge of UNIX isn't as good as it could be.

A program exists which might help solve this problem.  It's called
"screen" (possibly "GNU screen").  Its main purpose is to provide
multiple sessions on a single ACSII terminal.  Part of how it implements
that is to provide a virtual VT220 (or so) emulation.  If your
applications aren't really VT3xx-specific, they'd probably work under
screen.

I'll send a list of SCO binaries FTP sites under separate cover.  I know
a compiled "screen" is out there, but I'm not sure where, so you'll have
to search a bit.  (Try ftp.celestial.com first).  If you want to start
from source, it's somewhere out there -- try the usual UNIX sources
sites.  I don't know how difficult it would be to build.
