You could confirm it by decoding the bits -- or something?

I'm very enthusiastic and optimistic that I can finally use
my fixed-wireless-modem from linux instead of the pain of
M$-Win7.

Thanks for any advice.

OK, if you haven't touched PPP since the 1990's, then you might be forgiven
this problem.

Your PPP configuration is ancient, and expects to talk to a Hayes-compatable
internal modem. You don't have one of those.

Instead, your "fixed-wireless-modem" just converts from "serial" (on the
computer side) to wifi or phone (on the wireless side). That hash you see
at the expect is the PPP negotiation signal from the other end.

Get rid of the expect scripts. In fact, use something like the setup for
pppoe, which doesn't talk to a "modem" at all.
