HP doesn't yet have integrated support for X.25 in the ISODE release
thats publically available. I wouldn't be surprized if there IS X.25
code out there... but its not in 6.8 yet.

You will have to use the tsbridge facility in others/tsbridge to get
X.25 calls via another box, such as a Sun.

If you have documentation for a native sockets interface to X.25
then coding this up is trivial. Follow compat/ubcx25.c and compat/sunlink.c
for examples, modify h/x25.h with suitable code, and add address translation
routines into compat/x25addr.c.

It helps if the X.25 code can do fully async i/o, and supports the select()
system call properly.

If you have a non-sockets interface life is not so simple, but it CAN be
done. 

If you want any help with this ricky, my phone is always there.  I'm a
bit surprised your asking about isode-6.0, I installed ISODE-6.4 code
on at least one of your own CPU's over 8 months ago, but I guess
inter-departmental communications at U.Q are a bit cryptic at times.
