There are 2-3 products on the market that receive IR and output RS232.
I have used "IRman". It's inexpensive. It generates ASCII text (hex
characters). Each such data string is unique to a given button on a
given remote, e.g., 8FE3D56 might be channel-up on a remote for a JVC
model xyz TV.

There are others that do the same thing, but on USB.

I wrote AVR code that does the above, and also accepts data back from
the serial port (PC) and emits the same IR. That AVR (C and asm)
source code is a donated project on avrfreaks.net, in the projects
section. Look for "TWIRP".
