I've been playing around with PHP and my serial port recently, and I discovered that my computer will output 12V when the port is opened.
I'm not really sure how much power the serial port can supply. I was thinking of using a relay to power up other more power-consuming devices, still, I'm not sure if the serial port is strong enough to power the relay. Since I don't want to risk any of my computers motherboards, I need to be sure before trying anything.
And yes, I've seached on Google without any results.
