Important notice : TourViewer version prior to 1.1.0 show an error on launch under Palm OS5 . Palm OS5 does not load the serial library during start up as older versions used to. Therefore an error message is displayed when TourViewer is launched: "Can not load serial library." To solve the problem you can either install the latest TourViewer release or install Load Serial Library .

Thanks to Ulrich Riepert for this tip.


Only serial connections are supported. HAC4 devices with USB are not supported.
