It is a matter of putting the signal from where you are taking the -12V on low instead of high. RS232 codes "1" as -12V and "0" as +12V. Or perhaps you can feed the +12V from the power supply directly. > I still have the components knocking around and if anyone has a > suggestion for how to make the circuit work properly then I'm all > ears.

I have a nice Pinnacle Systems remote control which came with a RS232 dongle receiver. -- Herr Groucho ID Jabber: [EMAIL PROTECTED] Señal distintiva: LU5MJR - 144,550 MHz FM.
