##Overview## This sketch echos back characters received from the serial port to a socket client connecting on port 80.
It is an early part of a development effort to write a display controller for tricolor LEDs.
##Usage## Sending characters to the Arduino over serial stores them in a buffer.
Socket clients connecting on port 80 are replied with a brief Http header, followed by the contents of the buffer. If the client is a web browser, and the buffer contains valid HTML, the browser renders and displays this HTML.
##Parameters## Serial Baud Rate: 9600 bps
Maximum buffer size: 1024 bytes
