Motorola Phone AT Commands

From Wikipedia, the free encyclopedia

AT commands are used to control modems to do their specified functions. Cellular phones are not much different that the old dial-up modems that are still found in many computers. For this article we will begin focusing on the Motorola RAZR V3m from Verizon and the AT commands that this phone supports and their functions. Notice, however, that the Motorola ROKR Z6m also supports (at least some of) these commands.

Note that all these commands appear to be well documented officially on the MOTODEV site, which requires registration. Though the material applies specifically to the G24, it appears to also be relevant to other Motorola products (both GSM and CDMA).

AT Command	Response from Phone	Decscription of command
AT+GMM	+GMM: Motorola CDMA V3c Rev2 Phone	Display phone model information
AT+MODE?	+MODE: 0	Display current phone mode
AT+MODE=0	OK	Put phone in Modem Mode
AT+MODE=2	+MBAN: Copyright 2000-2004 Motorola, Inc.	Put phone in Phonebook Mode
AT+MODE=8	OK	On some P2K or P2K05 phones, puts the phone into P2K mode. This causes the current serial connection to the phone to be closed. The phone can be returned to the Modem mode by reconnecting it.

From MODE:2, an AT+CLAC command shows the following valid commands: AT+CLAC
