      java.io.PrintWriter
          ClientServer.TelnetPrintWriter

Enclosing class:

ClientServer

public class ClientServer.TelnetPrintWriter

extends PrintWriter

Extends the PrintWriter class to replace the println() method, so that it always prints a CR LF, which is required by the telnet protocol.

Unfortunately, this class has to reimplement all the constructors even though all that is needed is the re-done println() method. Feh.
