HelloWorld
======================

This example program will initiate communication with up to three ports.
The port number is automaticaly detected when using the USB connection on the SC4-Hub board.

//Required include files
#include <stdio.h>
#include <iostream>
#include "pubSysCls.h"

using namespace sFnd;

// Send message and wait for newline
void msgUser(const char *msg) {
        std::cout << msg;
        getchar();
