TCP/IP Stack

An on board IP/TCP/UDP stack has been integrated into the software negating the
need for the customer to implement one in their own code base.
This is accessible by using an embedded application (see section 9) using intrinsic
functions.

server.
Send/Receive TCP packets - Performs all TCP operations to send and receive
packets.
Send/Receive UDP packets - Performs all UDP operations to send and receive
