We downgraded to 3.7.2c3 because of the problem "could not negotiate a
compatible set of protocols....." with COMOS 3.8b17 The modem seems to
connect just fine but but no PPP connection can be established. We saw this
problem with a lot of different modem types which connected just fine
before.
I also noticed that sometimes these modem which have problems can connect,
but mostly not.
What's the bug here?
