lots of holes in my serial port self teaching
« on: August 13, 2009, 04:15:22 PM »
so i've been doing some research into serial port control. one thing i can't seem to find is an example of how a serial port outputs useful information. i know it outputs ones as negative voltage (a concept which causes my brain to bsod) and zeros as positive voltage and that it needs to be converted through something like a max232 chip to be readable by most electronics (0v for zero and +3.3v for one) but i'm stumped at just about everything else. anyone serial port knowlegable?
