I would be interested in seeing some "standard" for carrying X.25 on TCP/IP.
It would be useful being able to have multiple vendors X.25/IP products
talking the same language. I have my own version which I use when remote
applications wish to access my X.25 port on my Sun across the LAN. Does
your implementation allow for M/D/Q bits set in packets? Has Cisco 
documented how their implementation works?
