Notify of firmware support for port setting and baud rate
Simplify server input to accept anything
and send it on return (with linefeed!)
Support server output serial responses (not very pretty)
Setup only one LED and add serial setup stub
And serial setup debug
Move the globals up
Add some documentation and parse port and speed from API func
The meat and potatoes!
Pipe all incoming socket bytes into the serial port, and any incoming UART bytes into the socket.

Also blinks the LED while sending.. blink and you'll miss it.
Update readme to reflect changes (and remove ruby server)
