ANF10 network --> DN200 (RJE, Decnet) --> should be Ddcmp --Re - HECnet

18 Nov 2021

Point in this case is that the ddcmp is handled in Simh and not in system software so
software can only deal with packets/messages; there is need for a simh sync line where the
software itself will be able to communicate in bytes/characters and synthesize the
packets/messages as the next higher organization.

Well, a serial line over which DDCMP is running is purely a packet based interface.

  Indeed it is Ddcmp, but the meaning is the difference
between 
 packet/message oriented and character oriented and the latter should also exist.

 They speak DDCMP, yes, but not DECnet.  Any protocol layered over 
 DDCMP  should work.

    Indeed, and we just proved that with ANF10 which uses the DMCs and 
 DUPs but is not DECnet.
