   I am using Brixton PPP version 1.2 on a SparcStation 1+ clone with an
   Aurora Technologies 4-port sync card.  I am trying to connect with
   a Cisco router at the other end (don't know anything about it, except

I once connected 3Com NetBuilder and Cisco together with PPP.
Fortunately I had protocol analyzer, so I could see what
happens on serial line.

Cisco doesn't support any negotiation of parameters. If other side
tries to negotiate ANY parameter, Cisco discards request.

NetBuilder didn't negotiate any parameters in LCP -> no problem.

NetBuilder wanted to "negotiate" IP addresses with IPCP. Cisco
discarded request. NetBuilder was smart enough to try again
without any IPCP parameters, and IPCP got up. (However, when 
NB didn't get Cisco's IP address via IPCP, I had to add static
route for it.)

I have done this with Cisco software 8.? and 9.0.

My guess for your case: Brixton tries to negotiate some IPCP
parameters, and Cisco doesn't like it. Unnumbered interface on
Cisco might also cause problems.
