• http://www.irda.org/ The home of the IRDA standards organisation, somewhat messy, but they do provide the standards free for downloading. The narrow IrDa pulses use a pulse for every bit "1" on the RS232 interface and keep low for "0" bits, that's simple and easy, it requires a good sync, a pulse shapper and the decoding at the receiver. There are some standards, as the pulse width to be a percentage of the RS232 pulse.
• There's an application note entitled "IrDA-Compliant Transmitter/ Receiver," with lots of detail about the standard, at the SHARP web site, http://www.sharpmeg.com/datasheets/rf-ir/#0 and data sheets at http://www.sharpmeg.com/datasheets/rf-ir/#4
