Interesting, I didn't know such adapters were readily available. I really badly want to be able to control a CD changer from my empeg. Does anyone know if there's any projects out there that have successfully written free software to control any CD changer? If we could get that code running on empeg then what else would we need? From what little I understand, it would require some type of hardware to convert from RS232 serial to the proprietary signaling format.
