+CMGW - Write Message To Memory

"STO UNSENT" - message stored not yet sent (default)

"STO SENT" - message stored already sent

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)

After this prompt text can be entered; the entered text should be formatted

as follows:

- if current <dcs> (see +CSMP) indicates that GSM03.38/23.038 default

alphabet is used and current <fo> (see +CSMP) indicates that 3GPP TS

03.40/23.040 TP-User-Data-Header-Indication is not set, then ME/TA

converts the entered text into GSM/WCDMA alphabet, according to 3GPP

TS 27.005, 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 3GPP TS

03.40/23.040 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
