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, for example, the host program
might request a new status.
