AT Commands
AT commands are instructions used to control a modem. Many of them, initially used to control wired
dial-up modems, are also supported by 2G/3G modems and mobile phones. Besides this common
(basic) AT command set, GSM/GPRS modems and mobile terminals support an extended AT
command set, which is specific to the GSM technology. MobiLink currently uses internally such
extended commands for voice, data and SMS, but with this configuration page, you can send
commands directly to the wireless modems of the MobiLink IP equipment.
Some examples of such commands are shown below:
Get basic information about the mobile modem. Such information may be the name of
manufacturer (AT+CGMI), model number (AT+CGMM), IMEI number (International Mobile
Equipment Identity) (AT+CGSN) and software version (AT+CGMR).
