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
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-
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
