You connect the OmniGo to your PC via the serial cable.
You run the Clip & Go application in Windows on the PC.
You run the Clip & Go application in GEOS on the OmniGo.
Then, like magic, the clipboard on the PC and the clipboard on the OmniGo are one and the same. Anything you Cut or Copy on the OmniGo is automatically placed on the clipboard in Windows. Anything you Cut or Copy in the supported Windows applications is placed on the clipboard on the OmniGo.
Thus you can Copy data from supported applications like Excel, Lotus, Quattro Pro, Word, Word Perfect, or Ami Pro running in Windows on the PC... and Paste into the applications on the OmniGo. Or vice versa.
As far as I know, Clip & Go has nothing to do with faxing or telecommunications, except indirectly--in the sense that you could take data that has been transferred via Clip & Go and use it in your Windows applications that support fax or telecom.
