TEST MESSAGE
Note DTR signal is ignored, hence the indication is sent even if the DTE is inactive
( DTR signal is Low). In this case the unsolicited result code may be lost so
if MODULE remains active while DTE is not, at DTE startup is suggested to
check whether new messages have reached the device meanwhile with
command AT+CMGL=0 that lists the new messages received.
