// Compile this program with the following command line.
// C:>csc NStrSvr.cs
//
// To use this program with the companion client program, first start
// the server (this program), then connect to it using the client program
// in a separate console window.
// As you enter lines from the client, they will appear in the server
// console window. To end the session, press <Enter> on a blank line.
