First see if the Nokia allows setting up the modem to auto answer
the call.  In Hayes lingo one would send


where 2 is the number of rings after which the modem auto answers,
0 meaning don't answer automatically.

If this doesn't work, see if the modem tells you when a call comes
in, usually with the message RING (you can tell this by using tip
or cu to get an interactive session to the modem and then dial the
number of the Nokia from another line).

If the Nokia shows the RING message you can still have your
auto-answer by using the mgetty+sendfax port.
