Many people recommended Celeste Stokely's web pages at
I always knew of her fine Solaris modem pages, but she also covers PPP to
some length. From there, I downloaded pppd 2.3.5 (which is miles better
than Sun's asppp). I configured the router as a standard dialin router
while not including any modem-specific stuff, and I can now establish PPP
sessions at 9600 baud. I'm still getting junk on the line at 38400, but
I'm working on that ...
