There's not much to it, really.  You just need to clear out some of the
modem strings in the setup.  You can do this from the menus, or start off
with the following as your /etc/minirc.dfl file...

# Machine-generated file - use "minicom -s" to change parameters.
pr lock             /var/tmp
pu baudrate         9600
pu minit            
pu mreset           
pu mhangup          

Adjust the baudrate, and any other serial port settings, as appropriate.
You may also need to specify an alternative device name for the serial port
you'll be using, if the default /dev/modem symlink isn't set up or correct.

The above file works for me as is.
