Set command

The set command sends an RP-SMMA message.

The command is a trigger for the RP-SMMA message on the SMS stack to indicate to the Service Center that the User Equipment (UE) has memory available and can receive mobile-terminated short messages. The client can set a memory full situation preventing incoming SMS messages by acking a mobile-terminated short message with AT+CNMA=2 (the Protocol Data Unit (PDU) parameter has to contain cause code 22 "Memory capacity exceeded"). Cause 300 is returned for all failures.
