Exactly. As far as ppp is concerned, it's seeing CONNECT and testing
for carrier. Carrier isn't present ('cos your ISP has disconnected)
so ppp assumes that your hardware doesn't support carrier and
ignorantly continues, thinking that everything's ok.
With later versions of ppp you can insist on carrier with the ``!''
in ``set cd 1!''. Ppp will then notice that there's no link after
your ISP immediately drops it and will correctly close the modem and
notice the failure.
