This really belongs on comm-dev-forum.

Which version of Palm OS and which version of Windows?
Which IrDA protocol do you want to use?

I can't help with this part - I don't do windows. :)

So I guess you want to use IrLMP. Be sure you set up the Windows side to use
the same protocol. You need to do a connect at the LAP level and then a
connect at the LMP level after you discover and before you send data. Also,
you can't just make these OS calls sequentially. You need a state machine so
that you can proceed with each step only after the previous step completes.
You're notified when an action completes, and whether it succeeded or
failed, via a callback. You should retry at least a couple of times if a
call fails, either immediately or after a while.

The canonical example is Till Harbaum's IR Ping:

It lets you execute each step one at a time, letting you be the state
machine yourself.

You can download a StuffIt archive of a Mac CodeWarrior project. Use StuffIt
Expander for Windows:
http://www.aladdinsys.com/
to unstuff it on your PC and then look at IrConnection.c. It provides a
layer over IrLMP that lets you send arbitrary chunks of data back and forth
between two devices. It starts with a symmetrical connection: both sides
must initiate.
