Please have a look at these internet sites:
The UIR sends 6 bytes to the PC which represent the pressed button
The UIRT is an extension on the UIR. This device can also transmit IR.
The IRMan is almost the same as the UIR, but you don't have to build
Within a few months we (company Argolis) will also release a product
that can receive/transmit IR remote data and is also capable of SIR
(Slow IRDa). The firmware of our product can be updated at home.
