To use the IrDA protocols within Linux you will need to get a suitable copy of the IrDA Utilities. More detailed information about these and associated programs can be found on http://irda.sourceforge.net/ For more information about how to use the IrDA protocol stack, see the IR-HOWTO (http://www.mobilix.org/Infrared-HOWTO/Infrared-HOWTO.html) written by Werner Heuser There is an active mailing list for discussing Linux-IrDA matters called linux-irda.
