UUCP error message

[Lee Sailer]

I am trying to set up a connection between a ATT 6300+ V.2.0 and a
remote ATT 3B2.  The 6300+ is polling the 3B2.  The login succeeds,
but then I get:

Login successful: System=Bisnet1
Handshake Failed:  REMOTE REJECT AFTER LOGIN

So, what's this mean?

And more importantly, what books or manuals could you recommend so that
I could look this up instead of publicly displaying my ignorance 8-).
