17 | | M2M cellular modems operate as a point-to-point serial device. Typically they are used as IP network interfaces by initiating a connection to a cellular carrier using standard AT modem commands then running {{{pppd}}} which performs CHAP authentication and implements the PPP protocol. The {{{pppd}}} daemon uses the {{{chat}}} application for AT command scripts and creates a network interface once authentication succeeds. Some devices expose more than one serial interface for things like AT commands, proprietary API's, NMEA data from optional GPS etc can be used while the network is connected. |
