Transmitting a Byte Over Infrared to RS 232

[N468989]

does anyone know how what type of circuit i need to transmit a signal over InfraRed. the signal i want to transmit is for example one byte -> 1010 1010

the byte sent will be sent to a RS 232 port

i have a shift register with the data ready to be sent

i know that i need a IR photodiode and a phototransistor

:. sorry double posting

Before anyone gives Tko grief about double-posting, it was my suggestion that (s)he resubmit this here after I ran across it in General Physics. This seems to be a more appropriate location.
