A 6-digit numeric character key from 000000 to 999999.  Only incoming SMS with the first 6
characters matching with this key will be treated as a valid source of remote AT command.

This feature will not ‘judge’ the result of executing the command, so care has to be taken not to
enter improper command that make the modem becoming out of control:

1. Never send ‘interactive’ AT command by SMS, e.g. AT+CMGS=….
    This feature cannot return the prompt to the sender for second input

2. Always wait for the return SMS with AT responses  before you send another SMS AT command.

3. Currently commands created by OpneAT (e.g. AT+SMSAT) cannot be sent by SMS.
