Multi-Tech Systems CDMA Wireless Modem General Indicator +WIND

Chapter 3 – Unsolicited AT Result Codes
Multi-Tech Systems, Inc. CDMA Wireless AT Commands - PN S000294C 22
General Indicator +WIND
Description: This is a general mechanism to send unsolicited non-standardized indications to the
application. The identified unsolicited non-standardized indications are:
• Indication during mobile originated call setup that the calling party is ringing.
• Indication of the availability of the product to receive AT commands after boot.
The +WIND is overloaded with two functionalities:
1) posts non-standardized indications and
2) allows the user to specify indication level. For each of these indications, a “bit flow” has
to be indicated.
Values: <IndLevel>
1 (bit-0): R-UIM Presence
2 (bit-1): Reserved
4 (bit-2): Reserved
8 (bit-3): Indication that the product is ready to process all AT commands
16 (bit-4): Reserved
32 (bit-5): Reserved
64 (bit-6): Network service available indication
128 (bit-7): Network lost indication
256 (bit-8): Reserved
512 (bit-9): Reserved
1024 (bit-10): Corrupted RF calibration values (checksum mismatch)
Note 1: If <IndLevel> is equal to 0, no unsolicited “+WIND: <IndNb>” will occur.
Note 2: If <IndLevel> bit 10 is set, the modem will transition to OFFLINE mode.
A combination (addition of the values) is used to allow more than one indication flow. 0 < In
d Level ¡Ü 2047 For example: 128 (network lost indication) + 64 (network service available
indication) = 192.
The response is OK if the values are in the previous range.
The unsolicited response will then be: +WIND : <event>
Example Result
+WIND:8
Note: General indication that AT commands are ready to be accepted
The supported events are:
<event>
0: R-UIM not present
1: R-UIM present
2: Reserved
4: Reserved
16: Reserved
32: Reserved
64: The network service is available for an emergency call.
128: The network is lost.
256: Reserved
