perhaps you should start with the parallel port first, then
serial, then USB (optional: Game port). i learned this

after dealing with the hardware concepts, you can
easily program those ports using C, assembly, etc.
but now i'm using PHP with the DIO extension to

/dev/ttyS0 is the first pin of the serial port, right? What should I echo just to have one pin light up if I have a LED connected to it? Did I get the right concept? Is there a site/page for the signalling?
Thanks
