-----------GPRS/GSM for mbed at low cost for WEB connection/SMS/callings---------

I found a low cost GSM/GPRS module such this used in this project . http://finch.am/projects/arduinogsm/ it can be used for both SMS, calls and internet acess via GPRS for only $25

This module is a perfect add on to mbed for GSM communication

The only problem with GPRS connection to acess WEB  is that this module need to do the PPP negotiation for getting WEB acess

Using AT commands over serial port after doing the ATDT*99***1#   it get the CONNECTED, bellow is a sniff of serial port for the process to connect to site www.google.com and receive it. (using the module software)

Any one as the knowledge how the PPP negotiation is implemented?

According to the protocol  http://www.tcpipguide.com/free/t_PPPGeneralFrameFormat.htm . The frames start and end with 7E (Hexadecimal) flag as we can see below.

Any ideias are welcome for a kind of emulation  for get GPRS connections on mbed via serial port
