Response
TA selects the procedure, how the receipt of new SMS messages from the
network is indicated to the TE when TE is active, e.g. DTR signal is ON. If TE is
inactive (e.g. DTR signal is OFF), message receiving should be done as specified
in GSM 03.38.
Note1: If the DTR signal is not available or the state of the signal is ignored
(V.25ter command &D0), reliable message transfer can be assured by
using +CNMA acknowledgment procedure.
Note2: The rules <mt>=2 and <mt>=3 for storing received SM are possible only if
phase 2+ compatibility is activated with +CSMS=1
Note3: The parameter <ds>=1 is only available in phase 2+
OK
If error is related to ME functionality:
+CMS ERROR: <err>
Parameter
<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 old-
est indications may be discarded and replaced with the new re-
ceived 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.
3 Forward unsolicited result codes directly to the TE. TA-TE link
specific inband technique used to embed result codes and data
when TA is in on-line data mode.
<mt> Rules for storing received SMs depend on the relevant data coding me-
thod (refer to GSM 03.38 [2]), preferred memory storage (+CPMS) setting
and this value
Note: If AT command interface is acting as the only display device, the
ME must support storage of class 0 messages and messages in the
message waiting indication group (discard message)
0 No SMS-DELIVER indications are routed to the TE.
1 If SMS-DELIVER is stored in ME/TA, indication of the memory loca-
tion is routed to the TE using unsolicited result code: +CMTI:
<mem>,<index>
