Hi Glenn, No, the tracker works fine with a Serial to USB adaptor, I 
would just like to
eliminate the adaptor. The comport on the laptop may be faulty. I just 
got it yesterday at the
show. That is why I asked it there were any
port settings that anyone had used different from the virtual USB ports. 
Tnx for coming by yesterday, it
helped a lot..
