- Motorola phone AT commands
AT commands are used to control modems to do their specified functions. Cellular phones are not much different from the old dial-up modems that are still found in many computers. This article focuses on the Motorola RAZR V3m from Verizon and the AT commands that this phone supports and their functions. Other Motorola phones, such as the Motorola ROKR Z6m, also support some of these commands.
All of these commands are well-documented officially on the MOTODEV site, which requires registration. Though the material applies specifically to the G24, some are also relevant to other Motorola products (both GSM and CDMA).
Commands that start with AT+C are well-documented in the 3GPP standard TS 07.07 "AT Command set for GSM Mobile Equipment (ME)", which is also an ETSI standard and can be retrieved via their publications page.
Commands starting with AT+M are likely to be Motorola extensions.

This causes the current serial connection to the phone to be closed. The phone can be returned to the Modem mode by reconnecting it. AT+MODE=24 No response Put phone in USB mass storage mode. On some models, for instance the ROKR Z6m, this allows using the phone as a USB key.
