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.
