Sorry Scott, must of had some finger trouble and sent the message by
     mistake.

     To get a starter into what's required have a look at the Circuit
     Cellar Magazine (www.circuitcellar.com) Last year there was a couple
     of articles on IRDA ,October-November IIRC.

     I haven't looked into IRDA a great deal myself, but I have a friend
     who was recently working on a commercial product to interface a
     standard parallel printer to an IRDA compliant device.
     The only existing FULLY compliant device he could find was based on an
     Embedded PC!. He did say that it was possible to implement a subset of
     the protocol in a pic but speed and memory limitations are a problem.
     Speed could be solved with a scenix (although he would like them to be
     a little less 'flaky', to be used in a commercial product).
     Next time I speak to him I'll ask how he solved it. :)


     Dave

Were you attempting to respond to this message and inadvertantly hit the
