9.19.1Description
Sends one segment of a concatenated message from a DTE to the network (SMS-SUBMIT). The message
reference value <mr> is returned to the DTE for a successful message delivery. <Ctrl-Z> indicates that the
SMS shall be sent, while <ESC> indicates aborting of the edited SMS.
The command is supported only for text mode (+CMGF=1).
The entered text is preceded by a ">" (Greater-Than sign) character, and this indicates that the interface
is in "text enter" mode. The DCD signal shall be in ON state while the text is entered.
