Is any one using Aerofly Pro adapted to a USB connection? Just ordered this sim and from what I read the interface to use my own Tx connects to a nine pin serial plug. I have that on my desktop but would like to use it on my laptop (maybe practice a little at work when the boss isn't around). I'm using a 2.4 gig Compac Presario but it only has 2 USB and no serial. I'd probably need a USB driver from Ikarus I guess. Any suggestions?
