Just some Friday fun. Use the telnet program that comes with Windows and supports VT escape sequences.
import java.io.*;
import java.net.*;
public class AutoTelnet {
     private static Socket s;
     public static void main(String[] args) throws Exception {
          Thread t = new Thread() {
               @Override public void run() {
                    try {
                         s = new ServerSocket(5555).accept();
                    } catch (IOException ex) {
                         ex.printStackTrace();
          t.start();
          Process p = new ProcessBuilder("cmd", "/C", "start", "telnet", "127.0.0.1", "5555").redirectErrorStream(true).start();
          t.join();
          PrintStream ps = new PrintStream(s.getOutputStream());
          ps.println("Screen will be cleared in 5 seconds");
          ps.println("5");
          Thread.sleep(1000);
          ps.println("4");
          Thread.sleep(1000);
          ps.println("3");
          Thread.sleep(1000);
          ps.println("2");
          Thread.sleep(1000);
          ps.println("1");
          Thread.sleep(1000);
          ps.println("\u001b[2J");
          Thread.sleep(5000);
}
