3.1. General Procedures for PPP Setting
After the module registers on GPRS network, it is necessary to set the APN for PPP by AT+CGDCONT
and to start PPP by ATD*99#. After executing ATD*99#, the module will enter the PPP frame interaction
process, which is based on standard PPP protocol. The module data packet interaction description is
shown in the figure below. For more details about standard PPP, see RFC 1661.
