RS232 is a standard for serial communications. It sets up voltage levels for
logical 0 and 1, timming and waveforms that devices should provide to
receive/transmit data. A few weeks ago i built up and got worked a simple
RS232 device: a (old) terminal connected to the pc just for sending and
receiving chars. It was for college classes of digital circuits.

"(...) one learns how to write code by reading code. One doesn't learn how
ride a bike by reading a book, either." (Theo de Raadt)
"Man is driven to create; I know I really love to create things. And while
I'm not good at painting, drawing, or music, I can write software."
