Only for PDU mode:
AT+CNMA=<n>
Response
The write / execute command confirms successful receipt of a new message
(SMS-DELIVER or SMS-STATUS-REPORT) which is routed directly to the
TE. TA shall not send another +CMT or +CDS result code to TE until previ-
ous one is acknowledged.
If ME does not receive acknowledgment within required time (network time-
out), ME sends RP-ERROR to the network. TA shall automatically disable
routing to TE by setting both <mt> and <ds> values of +CNMI to zero.
Note: The command shall o n l y be used when +CSMS parameter <ser-
vice> equals 1 (= phase 2+).
1) If text mode:
OK
2) If PDU mode:
OK
3) If error is related to ME functionality:
+CMS ERROR: <err>
Parameters
<n> 0 command operates similarly as defined for the text mode
Reference
GSM 07.05
Note
If multiplex mode is activated (+CMUX=0) the +CNMI parameter will be set to
zero on all channels, if one channel fails to acknowledge an incoming mes-
sage within the required time.
