A quick search on Ebay shows some IRDA add-ons, mostly USB, some serial. Heres one($20.00): http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2041232359 You probably can't buy the parts for much less than this. Not sure if it has support under Linux, a few quick Googles showed some linux references. Most laptop/motherboard IRDA ports are preconfigured to just work, while the dongles require special initialization codes sent to them and proper RS232 handshake signals set to power them. Any serial-port dongle will just be SIR(slow infrared, up to 115200 bps). IRDA FIR is a different mode, typically at 4M bps, supported by some USB and built in IR ports. Google on "ronja" for a open 10Mbps 100 meter IRDA project that should keep you busy for the rest of the year :) I mentioned selling some home-made serial IR dongles previously, but I'm afraid I confused some people, the gadgets I make are for TV remote control, not for IRDA data transfers. They allow you to control your PC with a remote control or control your TV/VCR/stereo with your PC. The two use slightly different physical layers. You can sometimes do limited range TV remote control with IRDA SIR ports. See http://www.lirc.org, or my ugly web page at http://www.turbobit.com/lirc.html for more on TV remote control. I'm working on using a PC as a jukebox and a remote control as an interface to it. This sort of thing is gaining popularity with the new PC killer app "tv/video/recording..". And of coarse the 80G/$80 drives help :) Many of the new TV-tuner cards come with a remote control. Right now I have a cheap Win-TV tuner card($30-$40) that works good, I can record TV shows, do full screen TV, record from VCR tapes. I can't do TV out yet, keeping my eyes open for an inexpensive solution here. Maybe this sort of thing would make a good monthly meeting topic: multimedia stuff under Linux(linux is not just for networking geeks anymore!). Karl.
