GSP-1720 SDVM AT Commands
In addition to the AT commands that are defined in the SDM Integrators’ Manual, the SDVM supports the following commands:
AT&Wn User is allowed to save the current snapshot of parameter commands into two profiles (1 and 2). It is an error to save to profile-0 which contains the factory defaults.
n=1 (AT&W1) will save current AT parameters to user profile #1
n=2 (AT&W2) will save current AT parameters to user profile #2
n=0 (ATZ or ATZ0) will reset the AT table to factory default
n=1 (ATZ1) will reset the table to the user saved profile #1
n=2 (ATZ2) will reset the table to the user saved profile #2
AT+VTS Sends a single DTMF tone: 0-9, * or #. The UT must be in a call for this command to work.
AT$QCHFn where “n” is either 0 or 1. Sets the audio path to HFK (AT$QCHF0) or house kit (AT$QCHF1). Currently this command has not been tested as there is no HFK to test against.
