On most modern modems there is no need to have a PPP link between the Application Processor (AP) and the modem. They will often be able to transmit IP traffic directly to the AP.

Hence there is no PPP stack in phonet. If your modem does not support raw IP messaging (or any other datagram service) to the AP you will probably be stuck with good old PPP.
