A standard X.25 Interface?

[Henrik Ballermann]

Does anyone known of a standard X.25 programming interface to be used under UNIXSTREAMS? What I am looking for is a .h file describing operation (request, ack.
response and indication) and some describtion of use.

I am also interrested in a user X.25 procedure interface to be used by programs
in UNIX user space.

Please respond in mail, and I will give a summery.

Thanks
