Forgot to mention this in the article. If you attempt to build this,
make sure your TCP/IP headers have the appropriate

	#ifdef __cplusplus
	extern "C" {
	#endif

entries. Otherwise the linking will fail. An alternative is to modify
rmxtcpip.cpp in the following way: 

Replace

	#include <netdb.h>
	#include <types.h>
	#include <netinet\in.h>
	#include <sys\socket.h>

with

	extern "C" {
	#include <netdb.h>
	#include <types.h>
	#include <netinet\in.h>
	#include <sys\socket.h>
	}

Cheers,
