Hi James. Tanks for reply. It's been a hvile - I have no knowledge of this and lost interest in the matter. Now using Ubuntu 10.04 and allways latest Wine, but does not work. For others : Problem 1. IRDA protocoll must be working. First install in Ubuntu, so in Wine - I've heard ? The miniCD PolarIRDA (SigmaTel) contains Linux drivers, but I do not know howto..... On Mac it has to be on BootCamp i belive ? Problem 2. Polar PPT5 contains an updaterprogram accessable from "help-button". Also some url-links are, but none are working. I belive InternetExplorer are necessary to access the internet ?
