Hi Norman,
first of all think about the protokoll: How much circuitry do you want to implement?
the RS232 protokoll is not very flexible (it's ment to be a standard!), so if your IR protokoll don't uses one start bit, (5?-)7-8 Databit, Parity, Stopbit etc your only chance is the use of the control lines to create your pulse train. However I have no idea about your IR pulse timing but I would suggest you might get +-3ms accuracy (you will never know with windows (non realtime) systems) unless you don't write your own driver (and who wan'ts to develop hardware driver for windows?
😉next step would be a microcontroller as a translator to handle the IR timing and rs232 (since your company have a product with IR, maybe your R&D can build up that system quick
ly)
With a little luck, you might google something like a IR remote control with RS232.
have fun
