We have a network with one Kinetics FastPath and one Hayes InterBridge. The
CAP server is not visible on the other (non-KFPS) side of the InterBridge. I
have looked at the packets on LocalTalk, and the InterBridge sends a ZIP
query every now and then, but the KFPS ignores it. This is a major problem
for us.

I don't want to introduce new bugs, and it seems to be a litte bit
difficult to compile the gateway code (find a vax, use the right compiler,
convert to s-records etc). So, if anybody (Charlie?) has already done it,
could you please upload it to the CAP (listserv) server at cuvma, post
it, or mail it to me?

Thanks!
