4.3 Limitation and caution to be taken when using 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.
