Great work! I'd be interested in testing the windows version on cascaded my DM4800s
Also, have you looked at reading the DM's screen data every few seconds and displaying it?
I was looking at building an app to do it myself and mirror the DM's screen but haven't had time to get much done. Sending something like:
SYSX: F0 4E 7F 21 01 19 00 08 F7
SYSX: F0 7E 7F 07 03 7F 42 49 4E 20 6C 63 64 30 F7
returns the image data, though I didn't get as far as working out how to decode it.
