Although the RCX uses IR, it is not IrDA compliant.
The RCX operates using the same carrier (38kHz) found in many consumer
remote devices (television, VCR, etc). Aside from that it is non-standard
as far as IR communication goes. Simple - but non-standard - which means
it may be easy enough to build hardware and/or software to communicate
with the RCX, but its unlikely that anything will communicate with it
"off-the-shelf".
If you bypass the firmware and control the RCX IR hardware directly, you
can probably do some more interesting things with it. I don't think you
could do IrDA from a "purist" perspective, but you may be able to generate
something that is close enough to be accepted most of the time. The
problem is the 38kHz carrier - anyone know if it is generated in HW or
software? What about the RX side? I assume a bandpass at 38kHz, but
usually these are pretty wide.
