AT+a if auto-shutdown is off (ie RS232 on all the time). (Autosave)

AT+Gn

AT+G0 - turns off GPRS mode.

AT+G1 - turns on GPRS mode and selects the APN. (Autosave)

AT+I reports ASLH 306 firmware version number, RS232 auto off state (1 = always on), baud rate, N or E for parity. (F/W dependent)

AT+K Turns Sony Ericsson(™) module off. (Up to F/W version 2.11). Version 2.12 onwards turns off the complete modem.

AT+O Turns Sony Ericsson(™) module on. (Assuming modem is turned on). The AT+0 command is no longer implemented ie No turning on of the Sony Ericsson module on issue 3 hardware boards.

AT+P Power Consumption control. This command allows the modem to be set for either low or high power consumption. (P0 = low, P1 = high). P0 should be used when the DTE is unable to supply high current. P1 should be used when the DTE power supply current rating is not an issue.

AT+R Resets modem. (Up to F/W version 3.01).

Version 3.02 onwards causes the modem to execute a 10 second power cycle.

AT+S Displays Signal Strength, toggles on / off (default off). Remote AT+S reports last known Signal Strength.

From firmware version 3.02 the sample rate of the signal strength algorithm is increased.

AT+T Commands modem to dial a stored number held in “ME” memory location.

AT+n Set baud rate / parity. This is automatically saved.

When set to no parity, the Sony Ericsson(™) module will still respond to AT commands with even parity.

AT+0 9600 N81 AT+1 9600 E71 AT+2 4800 N81 AT+3 4800 E71 AT+4 2400 N81 AT+5 2400 E71 AT+6 1200 N81 AT+7 1200 E71 (Autosave)
