4.15 +CMGS - Send SMS Message
Exec Command: +CMGS=<length><CR><pdu><ctrl-Z/ESC> (PDU mode)
Execution command sends message from a DTE to the network (SMS-SUBMIT). In PDU mode, <length> is
the length of the actual TP data unit in octets; <pdu> is the GSM 04.11 SC address followed by GSM 03.40
TPDU in hexadecimal format.
PDU entry must be terminated by <ctrl-Z>. Sending can be cancelled by the <ESC> character.
Response is in the following format for PDU mode:
+CMGS: <mr>
where <mr> is the message reference value of the message.
If sending fails, final result code +CMS ERROR: <cms_err> is returned.
4.16 +CMGW - Write SMS Message To Memory
Exec Command: +CMGW=<length>[,<stat>]<CR><pdu><ctrl-Z/ESC> (PDU mode)
Execution command stores a message to memory storage <mem2> (<mem2> is selected by the +CPMS
command). In PDU mode, <length> is the length of the actual TP data unit in octets; <pdu> is the GSM
04.11 SC address followed by GSM 03.40 TPDU in hexadecimal format. By default, message status will be
set to ’stored unsent’, but parameter <stat> allows also other status values to be given.
PDU entry must be terminated by <ctrl-Z>. Storing can be cancelled by sending the <ESC> character.
Response is in the following format for PDU mode:
+CMGW: <index>
where <index> indicates the memory location where the message is stored.
If storing fails, final result code +CMS ERROR: <cms_err> is returned.
4.17 +CMOD - Call Mode
Set Command: +CMOD=[<mode>]
