Interactive Hardware Test Session for Maple
Connect via Serial2 (header pins D0 and D1 on the Maple) and press
'h' for a list of options.
To use this in a sketch, remove all the #includes and the function prototypes.

Maple overclocking hack
// Overclocking demo, written 05/19/2010 by bnewbold for leaflabs
// THIS COULD BRICK YOUR BOARD! OVERCLOCKING IS A HACK NOT A FEATURE!
// This code is in the public domain for all intents and purposes.
// Intended for use with libmaple on a Maple board. Concept from Thomas
// Jespersen: http://elec.tkjweb.dk/blog/2010/02/stm32-overclocking/

TTY/Serial Scalability Protocol Transport
==========================================
This document describes a new transport for the Scalability Protocols (SP). The
Scalability Protocols (as implemented in the nanomsg library) specify
lightweight protocols for common message-passing patterns in distributed
systems. They are specifically desgined to accomodate both new message types
and new message transports (as well as being completely agnostic to the content
or encoding of all messages).
