/** ********************************************************************
 * C/C++ Source: serialecho.h
 *
 * Class definitions for the SerialEcho and related classes.
 * This package requires the Serial, TTYSession and Thread classes
 * from the FSF Common C++ library (v 1.2.4 cplusplus.sourceforge.net)
 * 
 * SerialEcho is a monitor on the serial port which runs in its own
 * thread and is responsible for detecting and echoing any serial
 * input.  The class is based on the ttysession class so it can be
 * used as any fstream-like class
