I just purchased a Mitsubishi RPTV, and I'm trying to obtain discrete IR signals to change from one input source to another (instead of continually pressing the INPUT key to get to the appropriate input source). I have found Pronto codes for these discrete IR signals. However, I do not want to buy a Pronto. Instead, I would prefer to insert these codes (if possible) into my Palm V, and then in turn use the Palm to "teach" my remote control unit of choice. Does anyone know if there is a way to utilize the Pronto codes in my Palm?
