I *did* have tip working just fine, so I know that my /etc/remote setup is
okay.  Same goes for the ppp stuff -- it was working and all of a sudden
it wasn't anymore.

I gave this a try, but fsck didn't report any problems and nothing's
different.

Another tidbit of info: I have SD and RD lights on my modem... when I use
a terminal program on the mac and type in "AT", both lights flash
simultaneously for each character I press.  On the Unix side, the modem
shows no activity at all. 

Thanks to Bill for his suggestions, and please le me know what else I
might try.
