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

[R. Voorhorst]

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.
