The ppp. object represents the PPP interface of your device. This is the interface that uses one of the serial ports of your device and works with traditional landline or GPRS modems.
The ppp. object itself does not handle the PPP link negotiation, which is quite complex. This needs to be done in Tibbo BASIC/C code. For GPRS modems there is a very convenient GPRS library that implements the entire link negotiation process.
The ppp. object only specifies parameters related to the PPP interface and is not responsible for sending/transmitting network data. The latter is the job of the sock. object. You will find PPP interface listed or available on the following sock. object's properties:
