I have a SIMS digital voice recorder pen that uses a digital plug (like a cell phone earpiece) to output data from said mini-plug to a parallel port connector which obviously would plug in to LPT1.

My question is simply: "Can I write my own software to read the data and convert it into WAV files or whatever? Or should I give up now because its a proprietary device with private software embedded?

I have no other reason to do this than curiosity, so if its pointless, I won't bother. BTW- I have tried IO.DLL and other methods, but none seem to be compatible with XP. Thanks guys!
