"Q: What can I use the infra red port for?
A: There has been several discussions on this topic on the PowerList and on comp.sys.mac.portables. Users have been trying to get their PB1400 to talk to their new Pismo laptops, or other new gadgets. Some people have even been trying to change their television channels with the infra red port (this may sound crazy, but on more modern IRDA ports it is possible). The answer rather discouragingly is that you cannot do very much on with your PB1400 IR port. It only supports AppleTalk and is not IRDA complaint. This means that you cannot connect to the internet via your funky new Nokia or send documents to non-AppleTalk printers. You cannot even play IR networked Quake3 with your Pismo owning friends. What you can do is connect to an AppleTalk network with any other AppleTalk supporting IR port. That includes the PowerBook 3400, Kanga, 2400 and some of the earlier Duos. That sadly is about it. If you know of any cool things that you can do with your IR port then please drop me an e-mail as it would be fun to try them out and add them to the FAQ…"
