Serial port that modem is connected to []? ttyIAX0

Now we are going to probe the tty port.  This takes a few seconds,
so be patient.  Note that if you do not have the modem cabled to
the port, or the modem is turned off, this may hang (just go and
cable up the modem or turn it on, or whatever).

Probing for best speed to talk to modem: 38400
 OK.

This looks like a Class 1 and 1.0 modem.
