Old Lunchbox 8088, Datavue 25. It has an wireless keyboard that uses IR. I'd like to document the IR signal that each keystroke produces so that I can reproduce it from an IR emitter in order to allow me to interact with the machine if the keyboard ever fails or for other pointless but entertaining reasons.

I am aware of things like "learning" universal remote controls but I'm not too familiar with them and what data you can extract from them. I see I can buy USB IR receiver/transmitters for a modern PC, but I'm unsure if the software available will do what I'm looking for.

Is anyone familiar with the IR receiver/transmitter options available and whether they'll let me document the pulse frequency of each key press?
