The following serial commands are meant to emulate buttons on the remote control or DHD Con-
troller front panel. Each button has its own serial command, so effectively it is as if you were using 
the IR remote only you’ll be doing so via serial commands. These commands provide active OSD 
responses just like the IR remote.
