vince, I am going to be trying a USB to serial adapter to see if that will work or not. I have machines with serial as well, but since most of those netbook things have USB and thats an eventual plan to have in car at all times, figure I will try it now...
Hopefully get some time to play this weekend. I will report findings either way.
I have a few Serial to USB adapters at work to try, will probably try them all..
