Hi Wayback,
Thank you for the good advice. I connected the Gemini2 USB to my laptop. Device Manager did not make any change. I tried with 2 different cables. So my conclusion is the Gemini2 must have a broken connection or something fried.?
My next try is going to be the Serial/FTDI/USB cable method. Trying to get the right cable now.
Thanks again for all the other posters' comments and advice.
Roger
