Attempts to keep the system busy by passing data through a pipe in loop

This is a test of the C++ standard library. At present a port of the uClibc++
C++ library is available. Due to licensinging issues, the uClibc++ C++ library
C++ library is available. Due to licensing issues, the uClibc++ C++ library

Sends a repeating pattern (the alphabet) out a serial por continuously.
