The Little Black Box
The little black box is just that, it's a black box with 3 green/red LEDs a momentary switch and a DB-9 pigtail.
It's very dumb, and speaks only in status bits of the serial port. For instance, when the momentary switch is pressed the CTS bit on the serial port status is on. And when I kill the DTR bit, the green LEDs stop blinking (they start blinking when the serial port is opened)
Things to do:

Things to do:
- Figure out how to make it blink red
- Figure out what to make it do
