xPort / Curiosity / Windows Vista / 7 / x64 Compatibility Issue
For those people who are thinking of using xPort to multiplex GPS outputs to COM ports, be forewarned:

There is no driver available for 64 bit Windows (any version) at this time.

Without a driver, it might (did not on mine) run on Windows 7 64 but in 32 bit emulation mode that slows it down.

It is compatible with Vista x32 and apparently Windows 7 x32 if you run it as an administrator.

It will not work.

GPSGate have a 64bit driver. About
