+CMGS – Send message
Description:
The <address> field is the address of the terminal to which the message is sent. To send
the message, simply type, <ctrl-Z> character (ASCII 26). The text can contain all existing
characters except <ctrl-Z> and <ESC> (ASCII 27).
This command can be aborted using the <ESC> character when entering text.
In PDU mode, only hexadecimal characters are used (‘0’. . .’9’,’A’. . .’F’).

NOTE:
The message reference <mr> that is returned to the application is allocated by the prod-
uct. This number begins with 0 and is incremented by one for each outgoing message
(successful and failure cases); it is cyclic on one byte (0 follows 255).
This number is not a storage number – outgoing messages are not stored.
