F.4  Running TCP/IP Sample Programs

We have provided a number of sample programs demonstrating various uses of TCP/IP for net-
working embedded systems. These programs require you to connect your PC and the MiniCore 
module together on the same network. This network can be a local private network (preferred for 
initial experimentation and debugging), or a connection via the Internet.
