FYI. The simh 'sync' devices (DMC/DMR, DUP, KDP) can all interoperate. The
system at the other end of any 'sync' line can be anywhere the host system can
reach via IPv4 or IPv6. Transport can be TCP or UDP.
Simh simulators using the KDP and DUP run with simulated host based DDCMP implementations
and the DMC/DMR has imbedded DDCMP implementation. Rob Jarratt has done some testing
running these into his host based DECnet router.
Any of these 'should' be able to connect to a simh system which speaks Async DDCMP
over a serial line (DZ or VH) as well.

P.S. Cory - I'd love to see a DECnet compatible TOPS10 that runs on
simh, and the DEUNA seems like the only practical way to accomplish
that. The DUP/DMR emulation is interesting, but not that useful since
you need yet another 11/780 simulation for it to talk to!
Given that it?s DDCMP, it should work with any DDCMP device you can
connect it to. Connecting SIMH to a sync serial port may be difficult (hard to
find those) but async DDCMP is essentially the same and should work. That
means RSX or various routers or even (in theory, depending on digging up
some undocumented details) RSTS/E V10.
