Response 07 has been deprecated due to the new auto-on function. Whenever a valid
command is received (with two exceptions), the system will automatically enter the “on”
mode, if it is in standby. A client may still handle response 07, but it is no longer sent
from the host for any reason.
Response 10 will be sent when a normally valid command is sent to the host, but it
cannot be processed due to the system’s mode. For example, a database play will not be
processed while the system is in setup or options mode, AutoBuilding a changer, etc.
Note that a key press command will never return this response, as even audio transport
keys (play, stop) have alternate functions in various modes.
Unsolicited Status Events
Unsolicited status events can be sent to report the state changes of the McIntosh products.
There are two currently defined message levels: 5 - track changes, and 10 - all (including
1-second playing time updates). Clients are registered at level 5 by default. Clients may
change their message level using the ESCX7002 command. See the control commands
section for instructions on how to resister and unregister for unsolicited status event
levels.
