Problem is, as Wouter also mentioned, if you send a continuse
carrier for to long (and that's not long at all), most IR
receivers (as the TSOP range) with just shout down it's output.
You can't even send a continuse *modulated* carried, you
have to have a longer pause at intervalls specified in
the data sheets. The UART way of doing things isn't
very good for IR comms at all, IMHO.

And bit-banging a IR link isn't much harder then bit-banging a
normal serial comm.
