+/**
+ * <p>
+ * The simplest possible TCP network program, opening a socket and waiting for a reply. 
+ * It listens for any socket connection response, either from telnet (telnet localhost 2317)
+ * or another program that you write (which we will do later). 
+ * Once a socket connection is established, TcpExample1Telnet simply
+ * writes a string in response to that connection and finishes, exiting.
+ * 
+ * <p>
+ * As an alternative to running the Windows (or other operating system) console, 
+ * you can instead run the NetBeans terminal window.  If you are on Windows,
+ * NetBeans is looking for Cygwin installation (for Unix-like compatibility)
+ * with details at <a href="https://savage.nps.edu/Savage/developers.html#Cygwin" target="blank">Savage Developers Guide: Cygwin</a>.
+ * Modifying this program is the basis for Assignment 1.
+ * </p>
+ * 
+ * <p>
+ * Testing the running server program from telnet looks like this:
+ * </p>
+ * <pre>
+ * it154916:projects mcgredo$ <b>telnet localhost 2317</b>
+ * Trying ::1...
+ * Connected to localhost.
+ * Escape character is '^]'.
+ * This was written by the server
+ * Connection closed by foreign host.
+ * </pre>
+ * <p>
+ * Notice that "This was written by the server" matches 
+ * what is written by the code below, over the output stream.
+ * </p>
+ * 
+ * <p>
+ * After this first connection the program below drops to
+ * the bottom of the method, and does not repeat itself.
+ * In other words, the program exits.
+ * </p>
