I have personal experience with X.25 boards with X.29 pads built into
them, but I can't remember the !@#!$! board names.

One's French, and the other's Canadian (the Canadian company used to
advertise in UNIX Review, their name starts with 'A').

They both look like FIFO'ed serial boards and driver writing is fairly
simply (this is pretty darn high speed serial, though).  They (used to
anyway) release programming info without non-disclosure.

Sorry, I don't have more information, but the last time I placed with
this was on the DDN (Defense Data Network) and in connection to a
contract with the French Ministry of Defense (and their big upside
down U shaped building, which was almost all X.25).  This was way
back in 89/90.
