Got the next piece of the puzzle in place. I have designed my gizmo to transmit the two "send" commands that I previously viewed on the scope. Irrespective of which one I send the MX, in receive clone mode, sends back the response LSLSLSLS anywhere from 12 to 18 milli-seconds later. Just need to make a few changes to the gizmo to duplicate this and hopefully I can get a sending MX to dump its data. Then I'm going to need some software help. My son-in-law has volunteered but are there any others besides?
