That's more or less correct. Except that many modems these days don't use PPP, they expose a pseudo-ethernet port that's used for data communication and looks just like a real ethernet card. You send various manufacturer-specific setup commands to the modem via the serial ports, and then magically the pseduo-ethernet port starts transmitting and receiving data. In step (2) there's a lot more that goes on too, like finding out the access technology being used (GPRS, EDGE, UMTS, EVDO, etc) and getting network registration status.
