Switcher-Initiated Messages
When a local event such as power-up or a front panel operation occurs, the
switcher responds by sending a message to the host. The switcher-initiated
messages are listed in the following pages. The messages are underlined.
The switcher does not expect a response from the host, but the host program may
request a new status.
