Valid values for <stat> are:
PDU
Text
0
"REC UNREAD" received unread message (i.e. new message) (default)
1
"REC READ" received read message
2
"STO UNSENT" stored unsent message (only applicable to SMs)
3
"STO SENT" stored sent message (only applicable to SMs)
4
"ALL" all messages (only applicable to +CMGL command)
Response is in the following format for PDU mode:
+CMGL:<index>,<stat>,[<alpha>],<length><CR><LF><pdu>[<CR><LF>+CMGL:<index
>,<stat>,[<alpha>],<length><CR><LF><pdu> [...]]
where:
<alpha>: string type alphanumeric representation of TP-destination address or TP-
originating address corresponding to the entry found in the phonebook (optional field);
<length>: in PDU mode, this is the length of the actual TP data unit in octets (i.e. the RP
layer SMSC address octets are not counted in the length)
<pdu>: GSM 04.11 [8] SC address followed by GSM 03.40 [9] TPDU in hexadecimal
format.
Test Command: +CMGL=?
Test command gives a list of all status values supported by the A3LA-RM. Response is in the
form:
+CMGL: (list of supported <stat>s)
A.8.38 +CMGR – Read SMS Message
Exec Command: +CMGR=<index>
Execution command returns the SMS message with location value <index> from message
storage <mem1> (<mem1> is the selected message storage from the +CPMS command). If
status of the message is ’received unread’, status in the storage changes to ’received read’. If
reading fails, final result code +CMS ERROR: <cms_err> is returned.
Response is in the following format for PDU mode:
+CMGR: <stat>,[<alpha>],<length><CR><LF><pdu>
where:
<stat>:
0 - MT message unread
1 - MT message read
2 - MO message unsent
3 - MO message sent
(When reading an MT message the first time, the status is reported as 0 (unread). The
status is then changed to 1 (read), and that is reported on subsequent reads of that
message.)
