QEAV? 0xEB Command Packet:

The controller sends no

<Param> character in the

command packet.

This command causes the

CAT 860 to return a query

response packet where the

added <Param> character

contains the “enable” status

set by EAVS (<0xE0>).

Response Packet:

If the command is properly

received, the CAT 860

responds by repeating back

the command packet to the

serial controller with the

added <Param> character

containing the value

indicating the “enable”

status set by EAVS (<0xE0>).

The possible values are

shown below:

0x80 = TV/VCR Enabled

0x81 = CD/DVD Enabled

0x82 = COMPUTER Enabled

0x83 = AUX IN Enabled

If the command is not

received properly, the CAT
