Hi,
I am trying to connect with a WIN95 machine and the dialup
network to a FreeBSD box, running 22.7 and i4b 0.63.

It looks like WIN95 PPP is insisting on an async-map,
and thus the negotiation fails:

Anything which can done be about it? When I connect to
dialup equipment with debugging set on (Netblazer), I see
what Win95 is requesting:

    PPP PPP/Lcp Ack Rcvd; Processing Config Req, id: 2 
    lcp_request()

    id: 1 len: 20

It looks like WIN95 is request an async-map of 0x000a0000 ?

Now the question is: Did anyone succeed in connecting 
to a i4b server with Win95?
Or, can Win95 be told that it should not use an async
map over a sync HDLC connection.
Or, can I simply change the isppp.c-code to not send
a REJ?

Thanks!
