+CNMI - New Message Indications To Terminal Equipment SELINT 0 / 1
For compatibility with previous versions, Test command returns:
+CNMI: (0-2),(0-3),(0,2),(0-2),(0,1)
An enhanced version of Test command has been defined: AT+CNMI=??,
that provides the complete range of values for parameter <mode>.
AT+CNMI=?? Enhanced test command reports the supported range of values for all the
+CNMI command parameters.
Reference GSM 07.05
Note DTR signal is ignored, hence the indication is sent even if the DTE is
inactive (DTR signal is Low). In this case the unsolicited result code may be
lost so if MODULE remains active while DTE is not, at DTE startup is
suggested to check whether new messages have reached the device
meanwhile with command AT+CMGL=0 that lists the new messages
received.
+CNMI - New Message Indications To Terminal Equipment
SELINT 2
Note: the behaviour of command +CNMI differs depending on whether or not the improved SMS
commands operation mode has been enabled (see #SMSMODE)

AT+CNMI=[
<mode>[,<mt>
[,<bm>[,<ds>
[,<bfr>]]]]] Set command selects the behaviour of the device on how the
receiving of new messages from the network is indicated to the DTE.
Parameter:
<mode> - unsolicited result codes buffering option
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, otherwise forward
them directly to the TE.
2 - Buffer unsolicited result codes in the TA in case the DTE is busy
and flush them to the TE after reservation. Otherwise forward
them directly to the TE.
3 - if <mt> is set to 1 an indication via 100 ms break is issued when
a SMS is received while the module is in GPRS online mode. It
enables the hardware ring line for 1 s. too.
<mt> - result code indication reporting for SMS-DELIVER
0 - No SMS-DELIVER indications are routed to the TE and
messages are stored in SIM.
1 - If SMS-DELIVER is stored into ME/TA, indication of the memory
location is routed to the TE using the following unsolicited result
code:
+CMTI: <mems>,<index>
