I'm pretty sure I made some horrible configuration error at some point while upgrading.

Symptoms are as follows:

Modem worked fine with pon and poff before upgrade

Modem works fine with SuSE 8.1

I've re-run pppconfig with no good result

The modem's lights just sort of fibrillate

There's a pile of stuff about trying to load isdn modules on start up (I have plain old diallup, no ISDN)

Any ideas welcolmed. I don't really have an idea as to what I ought to be looking for, let alone how to fix it. And I really don't want to re-install.

If anyone wants any details, just tell me.
