<length> (PDU Mode)
Execution command sends to the network a message.
Parameter:
<length> - length of the PDU to be sent in bytes (excluding the SMSC
address octets).
7..164
After command line is terminated with <CR>, the device responds sending a
four character sequence prompt:
<CR><LF><greater_than><space> (IRA 13, 10, 62, 32)
and waits for the specified number of bytes.
Note: the DCD signal shall be in ON state while PDU is given.
Note: the echoing of given characters back from the TA is controlled by
echo command E
Note: the PDU shall be hexadecimal format (each octet of the PDU is given
as two IRA character long hexadecimal number) and given in one line.
Note: when the length octet of the SMSC address (given in the PDU) equals
zero, the SMSC address set with command +CSCA is used; in this case the
SMSC Type-of-Address octet shall not be present in the PDU.
To send the message issue Ctrl-Z char (0x1A hex).
To exit without sending the message issue ESC char (0x1B hex).
If message is successfully sent to the network, then the result is sent in the
format:
+CMGS: <mr>
where
<mr> - message reference number.
Note: if message sending fails for some reason, an error code is reported.
Note: care must be taken to ensure that during the command execution,
which may take several seconds, no other SIM interacting commands are
issued.
