Hello all. I have a serial port and made an object. my question is this. I have two variables which actually are two pins on the serial port: DataTernimalReady RequestToSend
Now I want to know if I set either of these to 'on' will they output voltage? Because I actually wan to use a RS232 to send voltage to a circuit. Anyone have any suggestions?

You will have to ensure that hardware and software flow control are set off for the serial port. The voltages will be off until the port is fopen()'d.
A useful discussion of the hardware end of using RS232 for power is at http://www.analogservices.com/rs232.htm
