Intel MD566X manual Event Reporting and Masking, Example 1. Viewing Supported Events

56K V.92 Data, Fax, and Voice Chipset

Table 6-1. Voice Mode Command Descriptions (Continued)

		Event Reporting and Masking: (cont.)
		Example 1. Viewing Supported Events:
		To determine what events are supported by the modem, send ‘AT+VEM=?’.
		AT+VEM=?
		‘C’ ← Feature Class
		DB860980 ← Playback mode events
		OFEE0883 ← Record mode events
		BB863EE0 ← Command mode events
		OK
		Example 2. Setting the Event Mask:
		To set the event mask, issue AT+VEM=m, where ‘m’ is eight hex digits. This com-
		mand is issued only in command mode and is followed when changing between
+VEM=m	see “m”	voice modes. That is, the modem uses the event mask previously set by the
		+VEM=m command when entering playback or record mode. The modem ig-
(cont.)
		nores any event bit set when that feature is not supported in that voice mode.
		AT+VEM=BB863EE0
		Example 3. Reading the Event Mask Settings:
		To read the settings for each event, type:
		AT+VEM?
		BB863EE0
		OK
		Example 4. Understanding the +VEM Hexadecimal Code:
		The following illustration shows how the hexadecimal eight-digit code
		(BB863EE0) is derived from the bit setting for each event:
		HEX DIGIT LOCATION:1 2 3 4 5 6 7 8
		EIGHT-DIGIT HEX CODE: B B 8 6 3 E E 0
