I want it, because it would be useful as part of a standard nightly modem
check to connect to each modem, verify the connect speed is something
reasonable, regardless of long-term connection characteristics, and verify
the start and execution of a valid PPP stream.

I would rather only do this connection once, rather than twice.  It would
also be nice to be able to extract the port information that I connect
to, which is what I'm working on now.
