Thanks RT.
Unfortunately your tricks won't work for me. I want to use ActiveSync via a USB cable to upload/download to a home theater Universal Remote Control MX-3000.
I received a very quick response from Parallels' tech support advising that Parallels doesn't support Microsoft ActiveSync in the current version, but that this feature will be avaliable in future version of Parallels. I had tried ActiveSync in both the 1970 Build and the 3036 Beta.
Oh well. It is a feature supported by Virtual PC 7.0. I guess I'll have to hold on to that old PowerBook G4 1.67 after all.
But, at the rate Parallels is improving their amazing software, i'm sure they'll eventually get ActiveSync to work.
