Multi-Tech Systems CDMA Wireless Modem manual General Indicator +WIND

Chapter 3 – Unsolicited AT Result Codes

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
512:	Reserved
1024:	Corrupted RF calibration values (checksum mismatch)
