In general, if you're having problems connecting to any
provider/service using PPP, test out the asyncmap first.  Some lines,
modems and/or RAS's have problems allowing certain control characters
through (^S/^Q are cited as obvious examples, which are the characters
which are escaped by asyncmap a0000: note the extra 0), so when
debugging a connection do set the option:

	asyncmap ffffffff

to escape ALL control characters.  This will increase the overhead on
your connection slightly, but then a 2% slower connection is better
than no connection at all, isn't it? :-)

Once your connection is working OK, you can start removing
(un-escaping) characters from the asyncmap one by one to figure out
exactly which ones you need to escape.
