Yikes, that's very misconfigured isn't it ;)  From what I've heard
about this problem I think it's due to the modem firmware not dealing
with ATH properly, rather than being a configuration issue.  Don't
know a great deal about this though, so willing to be educated.

Bah, rpms?  Google is my friend:

Good point, but I'm not sure a great deal of destination unreachables
should tear down a PPP connection?  As the ICMP will be over IP, which
is over PPP, so PPP has no "knowledge", for want of a better word, of
what an ICMP packet is.

Heh, I've got a downloaded copy of The Book of Liff somewhere ( and
the original in the parents' attic I think ), must re-read sooner
rather than later :)
