Note:
Any character sent by TE to G24 before G24 has reported a result of AT+CMGS
operation, will abort AT+CMGS command execution. However, if SMS was already sent
to network and sending operation was successful, the result of operation "+CMGS <mr>"
will be reported by G24.
A flex dependant enhancement enables the reporting of numeric error code to TE, in case
the sending operation has failed. The numeric error code will be reported in format:
"+CMGS ERROR: <err>".
