5.1.1.3. SMS TE2 emergency MO registration alert (AT$$EMMOREG)
This command is used for basic monitoring of TE2 condition. MT2 can be set to look for
$$TE2ALIVE command from TE2. If MT2 doesn’t receive $$TE2ALIVE command from TE2 within
the time frame as set by this $$EMMOREG command, MT2 will assume a problem exists at TE2.
MT2 automatically sends an SMS alert message to a user defined mobile number.
$$EMMOREG functionality is disabled after the first alert SMS message to prevent continual SMS
transmittal.
NOTE: To re-enable this feature the modem requires the $$EMMOREG Set command to be re-entered.
The applicable TI for this function is; 4098 (text message).
