want TCP/IP/token ring software for Xenix

[The Super User]

I am about to have the ability to put my xenix machine (SCO Xenix 2.2.1,
on an IBM PC/AT clone, 80286) on an ethernet by a new networking system
being developed by Bell of Pennsylvania and Carnegie Mellon University.

Their distribution test apparatus is for MS-Dos machines, or Unix
machines that support token ring, etc...

So, I need to get software for SCO Xenix that will support a token ring
card, and TCP/IP communication, e.g. telnet, ftp, ...

Any information would be most appreciated - I will summarize.
