4.9. DA2DVI-Pro initiated commands

4.9.1. EDID status changed

Description: This is sent after all commands that change the EDID (EDID copy,
EDID switch), or after a new EDID source ie. a new display device has been
connected to the DA2DVI-Pro.
Format:
Example:
Info: DA2DVI-Pro stores the last attached display device's EDID connected to DVI
OUTPUT 1. After disconnecting this device, its EDID will still be present in the
DA2DVI-Pro's memory, therefore no status change message is issued by the
DA2DVI-Pro if a display device having the same EDID is connected to that output.
(The same display device is connected again, or another display device (same
brand) from the the same manufacturer)
Info: To keep your application in sync with the DA2DVI-Pro, it is recommended to issue
a show validity ( {wv} ) → after receiveing EDID status changed response, and
read all locations indicating '3' in the table, as the EDID changes triggered the
'EDID status changed' response.

4.9.2. Port status changed

Description: If I/O port STATUS_TABLE has changed, the DA2DVI-Pro will send
this sequence to notify the controller software. This event is useful to trigger the
new {:ISD} and {:OSD} commands.
Format:
