<mode>

0     Buffer unsolicited result codes in the TA. If TA result code buffer is full, indications

can be buffered in some other place or the oldest indications may be discarded and replaced

with the new received indications.

1     Discard indication and reject new received message unsolicited result codes when

TA-TE link is reserved (e.g. in on-line data mode). Otherwise forward them directly to the TE.

is reserved (e.g. in on-line data mode) and flush them to the TE after reservation.

Otherwise forward them directly to the TE.

The rules for storing received SMS depend on its data coding

scheme, preferred  memory storage (AT+CPMS) setting  and  this value:

0     No SMS-DELIVER indications are routed to the TE.

waiting indication group (store message)) are routed directly to the TE using unsolicited result code:

+CMT:[<alpha>],<length><CR><LF><pdu> (PDU mode enabled); or

+CMT:<oa>,[<alpha>],<scts>[,<tooa>,<fo>,<pid>,<dcs>,<sca>,<t osca>,<length>] <CR> <LF><data>

(text mode enabled, about parameters in italics, refer command Show Text Mode Parameters AT+CSDH).

3     Class 3 SMS-DELIVERs are routed directly to TE using unsolicited result codes defined in <mt>=2.

Messages of other data coding schemes result in indication as defined in <mt>=1.

<bm>

(not used in CDMA/EVDO mode)

The rules for storing received CBMs depend on its data coding scheme, the setting of Select

CBM Types (AT+CSCB) and this value:

0     No CBM indications are routed to the TE.

2     New CBMs are routed directly to the TE using unsolicited result code:

+CBM: <length><CR><LF><pdu> (PDU mode enabled); or

+CBM: <sn>,<mid>,<dcs>,<page>,<pages><CR><LF><data> (text mode enabled)

<ds>

(not used in CDMA/EVDO mode)

0     No SMS-STATUS-REPORTs are routed to the TE.

1     SMS-STATUS-REPORTs are routed to the TE using unsolicited result code:

+CDS: <length><CR><LF><pdu> (PDU mode enabled); or

+CDS:    <fo>,<mr>,[<ra>],[<tora>],<scts>,<dt>,<st> (text mode enabled)

2     If SMS-STATUS-REPORT is stored into ME/TA, indication

of the memory location is routed to the TE using unsolicited result code: +CDSI: <mem3>,<index>.

<bfr>

0     TA buffer of unsolicited result codes defined within this command is flushed to the TE

when <mode> 1 to 2 is entered (OK response shall be given before flushing the codes).

1     TA buffer of unsolicited result codes defined within this command is cleared

when <mode> 1 to 2 is entered.

 

Example

AT+CNMI=2,1 (unsolicited result codes after received messages.)

OK
