GRRRRRR!
I must be the biggest-stupid head ever!
I just spent two hours updating Windows so that I could run the Open Source Controller interface.
Only AFTER doing this, did I realize that I did NOT have a SERIAL port on that computer!!!!! I had an old-school printer parallel port, but NOT a serial COM port!
Doh!
Now I am working on another computer to try to get the right software updates and get the controller rolling!
EDIT:
Gal dern it!
Trying to load the Microsoft Net Framework has now made Internet Explorer lock up any time I try to open it! Without Internet Explorer, I can't even go to the web and download Firefox!
I can't load the software at all! On to another computer! (Number four, counting using Tom's computer yesterday...)
