Sockets are stateful without connections.

On the subject of close() and reason now why any such classes should not 
implement java.lang.AutoCloseable? Idempotency not withstanding.

Anyway for the sake of narrowing this thread her is the interface I'm 
asking the user to implement: -

/**
  * Copyright Tier3 (c) Software. All rights reserved.
  *
  * Contract for user class that will specify and process
  * the server handshake.
  *
  * @author    Richard Maher
  * @version   1.0
  *
  */

package tier3Client;

import java.awt.Color;
import java.lang.AutoCloseable;

interface Tier3Handshake extends AutoCloseable{

     String   getSalutation();

     boolean  setResponse(String remoteResp);

     void     setRcvd(int bytes);

     void     setSent(int bytes);

     void     setRefCnt(int pages);

     void     appendMsg(String msg, Color color);

     void     appendMsg(String msg);
	
}
