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.

This sounds exactly the same as the code from the University of British
Columbia. In what ways does it differ?

have said "We, at the University of British Columbia, have ....". The code
I mentioned at that of UBC is one and the same. Sorry for the omission.
