Chapter 7 – Status Commands
Multi-Tech Systems, Inc. CDMA C1 AT Commands Reference Guide (PN S000478C) 20
Chapter 7 – Status Commands
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.
Syntax: Command syntax: AT+WIND=<IndLevel>
Command Possible Responses

Values: <IndLevel>
1 (bit-0): Reserved
2 (bit-1): A calling party is alerting
4 (bit-2): Product is ready to process read-only AT commands
8 (bit-3): Indication that the product is ready to process all AT commands
16 (bit-4): A call <idx> has been created (after ATD, +CCWA, etc.)
32 (bit-5): A call <idx> has been released (NO_CARRIER, ATH, etc.)
64 (bit-6): Network service available indication
128 (bit-7): Network lost indication
256 (bit-8): Reserved
512 (bit-9): Shut down complete
1024 (bit-10): Corrupted RF calibration values (checksum mismatch)
2048 (bit-11): Reserved
4096 (bit-12): Reserved
8192 (bit-13): Reserved
16384 (bit-15): SMS service ready indication
Note 1: If <IndLevel> is equal to 0, no unsolicited “+WIND: <IndNb>” will occur.
Note 2: The power off indication, +WIND=10, will occur even if +WIND is equal to 0.
A combination (addition of the values) is used to allow more than one indication flow.
0 Ind Level 32767.
For example: 128 (network lost indication) + 64 (network service available indication) = 192.
The response is OK if the values are in the previous range.
