I have this old PC-serial IrDA receiver (Puma Technology) that I got as 'prize' a while back. I've always felt that it probably should work with the Mac - the hardware is surely the same with the same serial-connection concept. I can connect PC-serial to USB via a Palm-cable and Keyspan Dual Serial - and I know that IrDA is turned off as a Network function in my G4 in OSX. But does anyone out there think I have any chance of making this thing work in X (or even 9.2) - and if so do you have any pointers as to how or where to learn more?
