maybe this info can speed up the proces of someone else
it took me a long time to figure out how to use the incoming signals in riderunner (newbee)
I use the signal DSR to auto popup the cameraskin
"ONDSR_ON","LOAD;APP.SKIN;Road Camera HD Version: 0.3.0.0;C:\Program Files\Long Range Communications Inc\RoadCameraHD\Road Camera HD.exe;!WindowsForms10.Window.8.app.0.378734a"
these two lines i put in ExecTBL.ini
when the line goes high (reverse light) the camera pops up line low and it exits to previous screen
I made a simple buffer to protect the serial port
