(PDU Mode)
AT+CMGS=
<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).
