Don't know specifically about the Apple modem, but I'll wager it sets  
itself up as a /dev/serial.something device, as the USB<>serial  
converters do.  Once you find the device, you can use minicom or ZTerm  
or similar to connect to it just as you describe - they have a place  
in the config to identify the device.

I *really* wish someone would do a Cocoa terminal like iTerm that  
knows how to talk to serial devices.  ZTerm is very dated (like 10.1  
dated), and all the alternatives I know of are enterprise class $100+  
apps with fancy terminal emulations.  I just need to talk to routers,  
etc. on a semi-regular basis.
