It's been a while since I did this, but here goes.

Is this modem for incomming or outgoing calls, it may make a differance on how 
to configure it.

There is some info in /etc/inittab, and I think setserial is used to set port 
parameters, but most of it should be able to be defined on the line in 
inittab.

Hope this helps some, Mike
