+CMGW - Write Message To Memory
SELINT 0 / 1
into GSM alphabet, according to GSM 07.05, Annex A; backspace can be
used to delete last character and carriage returns can be used.
- if current <dcs> (see +CSMP) indicates that 8-bit or UCS2 data coding
scheme is used or current <fo> (see +CSMP) indicates that GSM 03.40
TP-User-Data-Header-Indication is set, the entered text should consist of
two IRA character long hexadecimal numbers which ME/TA converts into
8-bit octet (e.g. the ‘asterisk’ will be entered as 2A (IRA50 and IRA65)
and this will be converted to an octet with integer value 0x2A)
Note: the DCD signal shall be in ON state while text is entered.
Note: the echoing of entered characters back from the TA is controlled by
echo command E
To write the message issue Ctrl-Z char (0x1A hex).
To exit without writing the message issue ESC char (0x1B hex).
If message is successfully written in the memory, then the result is sent in
the format:
+CMGW: <index>
where:
<index> - message location index in the memory <memw>.
If message storing fails for some reason, an error code is reported.
Note: care must be taken to ensure that during the command execution, no
other SIM interacting commands are issued.
Note: it is possible to save a concatenation of at most 10 SMs; the
maximum number of chars depends on the <dcs>: 1530 chars if GSM
03.38 default alphabet is used, 1340 chars if 8-bit is used, 670 chars if
UCS2 is used
Reference GSM

Note
To avoid malfunctions is suggested to wait for the +CMGW: <index> or
+CMS ERROR: <err> response before issuing further commands.
