You're right, I just sent before thinking hard enough.

Another poster suggested that it's the inversion that causes the problem.
I'm not sure about this; what's the idle state of the IR receiver module?
The USART expects idle high, and that's what most modules produce.

Also a good idea to check the stability of that idle state.  Do you get a
lot of noise, or is it rock solid until IR data comes in?

Once more I'm going to state my support for a more common IR comm
scheme- NRZ or pulse length.  I find pulse length to be easier, but that's
just me.
