The University of British Columbia have added a CCITT socket domain to
4.[23] BSD UNIX to support an X.400 messaging system. It uses the sync.
port of a DMF32 and I understand it should also work on a Sun with one
of the RS232 ports configured for synchronous communication.

Sun also sell X.25 for their SUNlink product: it also provides socket
level communication (based on UBC code?) The SUNlink board has some
intelligence and should manage a good bit of the X.25 processing.

Well, in section 1m of our HP9000 manuals there is a getx25 command.
This configures getty for reverse pad ports. The entry makes reference
to a HP pad, but I don't know if this is a box or just another card
that slots into the backplane. I'd guess this offloads X.25 and triple-X
from UNIX entirely, so probably doesn't count.
