= Command response
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 Escient 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.
