Developing software for Motorola m333X25, using X.25 API

I'm searching for software developers familiar with the Motorola
MVME332X25, an intelligent VME based X.25 communication controller,
used in Motorola Delta series UNIX systems.

The company I'm working for has very good experience with this X.25
communication controller, to support remote logins from the Norwegian
X.25 PDN. The controller also features an X.3/X.28/X.29 PAD software,
both for dial-in and dial-out.

So far so good, but I have to rewrite part of my software,
a communication protocol with the local stock exchange, to run with
this communication controller instead of leased-lines.

The X.25 driver and API manual supplied with the card, doesn't
really make it tempting to rewrite my software, since all the
library functions, deal directly with X.25 and not the higher PAD
levels. 

Do I really have to mess with all the X.25 link level and
packet level stuff, and the buffered pipe protocol (BPP), when all
I want to do is to open an VC, supply an X.121 address, user data and
then use UNIX read() and write() to implement the ASCII based
communication protocol ?


Anyone from Motorola out there ?
