a wireless serial link requires surgery to IC. the HB side woudn't be
bad. on the ic side you'd have to plug into the board comms routines
(probably most are stashed away in a single library) and substitute
your own code that deal with transmission errors etc.
the bandwidth of the sony-ir protocol is only about 600 baud. also it
is unlike rs232 serial in that it is not constant time per bit (bits
are encoded by length between ir pulses). so it would be a little
tricky to solve just by plugging into the serial port of your host,
unless you drop the bandwidth to 300 baud.
we're starting to play with IRDa devices at my lab. these are
115Kbaud serial links. really cool, just plug n play replacements for
a serial link.

| OK, so now we can send and recieve sony IR transmissions. This is so totally cool I just can't believe it. But you know what would make it at least 10E23 times better? If I could re-direct IC so as to not use the serial port, but to use the IR port (...) (29 years ago, 20-Feb-96, to lugnet.robotics.handyboard)
