Hi Pete,
Thanks for your quick reply. My Device Manager tells me that I have two ports, Communication Port (COM1) and USB Serial Port (COM2). My GPSout is connected to COM2. I have FS9 and FSX on my new computer with VIsta 64. FSX works fine and sends GPSout signal to COM2 and I can use my AvMap EKP-IV, so I know that COM2 works fine. When I switch to FS9 GPSout do not work (I prefer FS9 over FSX - faster and more reliable). I have two different FSCUIPS for each FS. Never had any problem with GPSout on any of my computers until VISTA (do not like this windows - hard to find anything there).
Pete do you need any other info about my setup to help resolve this little isue. I do realy appreciate your help. Thanks.
