The command structure for mute and mute status requests
are listed below.
When the AV-452 receives a command for a channel mute,
it will reply with a status command of the new status,
indicating the change was made. Status commands are
also generated whenever the function changes. For
instance, if someone presses the MUTE button for channel
1, uses the IR command or relay control to toggle MUTE 1,
or uses an RS-232 command to change MUTE 1, the AV-
452 will generate a status command on its own. This
reduces the need for recursive scanning routines.
