I just booted into Parallels XP bootcamp partition and installed MS Active Sync 4.2. I had a beast of time finding it, with Windows Vista arriving they are phasing out that version and they are rearranging all their links.
Then I plugged my QTek 9100 in, and nothing happened. Hmmm. Oooh… click usb icon in Parallels bottom bar, select USB serial for Wizard, and woopdiedoo, I got a connection.
Now synchronising… It’s nice when technology just works !
