a simple NPN transistor circuit (Always off until
voltage applied) where the signal from the serial port is connected
to the base of the transistor and when it sees the +5v the path from collector
to the emitter (the +12v from the power line form inside of the computer) is
created. GREAT diagram on the transistor circuit on this website:</span></font><o:p></o:p></p>

just need a program in linux to send the +5V signal. Simple and about $5
