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://www.cs.uit.no/~dagb/irda/. For more information about the IrDA protocol stack, see the IR-HOWTO written by Werner Heuser There is an active mailing list for discussing Linux IrDA matters called linux-irda. To subscribe to it, send a message to Majordomo@list.uit.no with the words "subscribe linux-irda" in the body of the message, the subject field is ignored. Dag Brattli
