Usually the COM2 port of a computer can perform the IRDA function. (tht is your IR data link) on most laptops IRDA port is directly available but on a PC you would have to change your BIOS settings to make COM2 ready for IR link &b ofcource you would need a suitalbe connector.

Have a look at http://www.lirc.org/receivers.html for building an IR receiver and http://www.lirc.org/transmitters.html for building an IR transmitter. Both the receiver and transmitter are erally simple devices which can easily be built into the same device.

That will give you your physical device for RX and TX but you will still need to set up your computers bios for IR on com2.

Normally you'll find the IR setting in the peripherals section of you bios.

I've built the Lirc Receiver/transmitter and it works great. Have fun.
