The controller sends no <Param> character in the command packet.

Response Packet:

The CAT 860 sends only one <Param> character in the response packet. The possible values are shown below:

0x80 = IR Channel A

0x81 = IR Channel B

This command causes the CAT 860 to return a query response packet where the <Param> contains the selection status set by IICH (<0xB0>).

If the command is not received properly, the CAT 860 responds by sending a <NACK> character.
