[net.lan] Connecting lans

lee@cosivax.UUCP (11/09/84)

We are attempting to network all of our in-house machines, which 
basically fit into two categories, DEC-like and IBM machines.  We 
are installing Ethernet for the DEC type machines, a Vax 11/750
and several 68000 supermicros.  The IBM machines, 6 Series/1 minis,
have several networking possibilities, all of which use synchronous
protocols, sdlc, hdlc, or bisync.  All of our systems are running 
Unix, and have an implementation of TCP/IP.  

The big problem is interconnecting these two groups of machines.
Our current thinking is to use a DUP11 synchronous board on the
750 connected to one of the Series/1.  In looking through our 4.2
distribution, I am unable to find a driver for a DUP11.  Does anybody
have or know of such a driver?  

I would be glad to hear other peoples experiences and/or suggestions
concerning this problem.  Please respond by mail, and I will summarize
on the net if there is enough interest.

Re: DUP11 driver

A DUP11 driver is supplied with the UREP (Unix RSCS) package from Univ
of Pittsburg.

UREP (UNIX RSCS Emulation Program) is from Penn State University.  Send mail
to dae@psuvax1.UUCP for more information.  It may not be what you need, unless
you are building an RSCS local- and/or wide-area-network.  Such networks use
the RSCS (Remote Spooling Communications Subsystem) protocol and can include
IBM machines running VM, VAX systems running VMS, and anything with UNIX (as
long as it has a UNIBUS and a DUP11 or you're willing to write your own device
driver).  It works over channel-to-channel adapters (between IBMs), over DECnet
(between VAX/VMS systems), and over bisync lines (all combinations).  Send mail
to me for more on RSCS.
