Yep.

While we're back to the subject of IR remote controls, does anyone know of a
source for the IR transmitter/receiver chip set so that I can make my own
system similar to the ones used in audio/TV devices?  They have to be cheap,
as they're so ubiquitous.

Short of ripping a VCR and controller apart to find out what they use in the
transmitter and receiver or buying a service manual (and probably getting
cryptic Japanese part numbers!), how do I get the encoder/decoder chips sets
and find out what the encoding standard(s) are?

If you can point me to the parts and spec, I'll help you to interface them
to a RS-232C port.
