Demonstrates how to create a TCP/IP socket, listen on a port, accept an incoming connection, and send a "Hello World" message to the client.

Note: This example requires Chilkat v11.0.0 or greater.

# This example will listen at port 5555 and allows for a backlog
# of 25 pending connection requests.
