Well, HELP suggests the following
sim> help dmc config example
Device DMC is currently disabled
DMC help. Type <CR> to exit, HELP for navigation help
Examples
To configure two simulators to talk to each other use the following
example:
Machine 1
sim> SET DMC ENABLE
sim> SET DMC0 PEER=LOCALHOST:2222
sim> ATTACH DMC0 1111
Machine 2
sim> SET DMC ENABLE
sim> SET DMC0 PEER=LOCALHOST:1111
sim> ATTACH DMC0 2222
You should be able to confirm that this is sufficient if you try connecting
DMCs together when running 'known to work' OS configurations (these include VMS
and RSX).
Meanwhile, since RSTS's drivers (or network startup code) have issued warnings
about problems with the version of the device we can't really be sure that it
is actually starting up the device. The DMC device simulator won't try to
connect to the peer until the simulated OS brings the device online.
If someone has RSTS DMC11 device driver source we could determine the details
of the version requirements and/or other behavior that it needs.
