Yup.
 We have a running TCP/IP link between Norway and Sweden on two
Bull DPX 2/320's. It is not a point-to-point link, but a simulated multi-
node network. Bull's own little unix (B.O.S) supports TCP/IP over
X.25 with extensions to some existing commands. This is the way we did it:
(Simplified)

Both machines has the following entries in their /etc/hosts:
swbull_ix0	125.0.0.1
medoc_ix0	125.0.0.2

swbull> ifconfig ix0 swbull_ix0 publix x121 <swbulls number>
swbull> route xadd bull_ix0 <swbulls number>
swbull> route xadd medoc_ix0 <medocs number>

medoc> ifconfig ix0 medoc_ix0 public x121 <medocs number>
medoc> route xadd bull_ix0 <swbulls number>
medoc> route xadd medoc_ix0 <medocs number>

If we would want to connect more machines to the same network, we would
simply add some more hosts with 'route xadd'.

It works rather Ok, but it is *SLOW* due to the 2400 BPS modem on
medoc's side. We will soon upgrade to 9600 on medoc and that will
probably help the performance a bit.

B.O.S. does not support UDP/IP over X.25. The reason for this is
probably that nobody should get the very, very sick idea of running
NFS over X.25.

Mail me if you want the more pervert details of this installation.
