In PDU mode: (+CMGF=0):
+CDS: <length><CR><LF><pdu>
The following table shows the +CDS parameters.
After sending a +CDS unsolicited response to the TE, the G24-L will expect a +CNMA (new
message acknowledgement) from the TE within a predefined timeout of 60 seconds. The G24-L
will not send another +CDS unsolicited response to the TE before the previous one is
acknowledged. If the +CDS is acknowledged within the timeout, the new SM is not saved in the
message storage. If the +CDS is not acknowledged and the timeout has expired, the new SM is
saved in the message storage and +CNMI parameter <ds> is set to ’0’.
