Nope. Modem works fine. I can talk to the device, dial out manually, all
the usual stuff. (And of course it's still working OK under Windows.)

Been through all this multiple times, and also have invoked pppd several
ways. I couldn't have made the same mistake everywhere.

No authorization necessary. After going through the usual vanilla script
logon manually (which works fine) I see the ppp packets coming from the
other end. In fact, if I understand the messages in /var/log/messages
correctly (always a big IF) ppp actually correctly sets several
configuration parameters and completes the set of initial handshakes. It
only dies _after_ that. I think.
And, of course, Windows is working just fine.

Again, don't see how, if only because Windows is happy.

'Tis indeed the most likely. I bet that there's some weird trivial
configuration parameter that has somehow got tweaked.

Will do this. noauth, defaultroute are already there.

Well, doesn't "noauth" turn all this stuff off? I mean, I don't have any
kind of a shared secret with my ISP, just the usual password at login time,
so I don't see that any kind of further authentication is needed or even
possible.

Not sure exactly what you mean. That's how I was logging in when the
problem first appeared.

I've been doing it by hand, since that seems like the "closest to the
metal" with less of a chance for something else to get in the way.

I don't think its their fault. I'll check with some other Linux users in
the area, but I doubt that US West has been stupid enough (although I admit
that they certainly do some pretty stupid things) to break Linux access.
I'm not trying to put down any of the suggestions; just trying to explain
where things stand. I tried a LOT of things before posting the request for
help. (I mean, how hard can this stuff be, right?)

First place I looked.
I'll try the other suggestions. Most of the documentation I've come across
is about getting the modem configured correctly and/or being able to talk
to the modem through the serial port, etc. All that seems to be working
fine.

It's going to turn out to be something really, really stupid. I just know
it....
