Masalah klien telnet Android

Saya baru dalam pengembangan di OS Android. Saya mencoba mengembangkan klien telnet saya untuk OS Android. Sekarang, saya hanya mencoba menghubungkan server telnet, dan menerima pesan login.

Tetapi ketika saya memulai soket untuk menghubungkan server telnet saya menerima simbol aneh ??????!???? alih-alih pesan logon dari server telnet.

public class MainActivity extends Activity {
    protected static final int TCP_SERVER_PORT = 23;
    protected String inMsg, str;
    static Editable sentence;
    static String modifedSentence;
    BufferedReader inFromUser;
    Socket clientSocket = null;
    DataOutputStream outToServer=null;
    BufferedReader inFromServer=null;        

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button startButton = (Button)findViewById(R.id.startButton);
        final TextView textView = (TextView)findViewById(R.id.textView);

        startButton.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View arg0) {
                new Thread(new Runnable() {                   

                    @Override
                    public void run() {             

       //Create socket
        try {
        clientSocket = new Socket("192.168.1.1",23);
       //Create out stream for ClientSocket
            outToServer = new DataOutputStream(clientSocket.getOutputStream());
       //Create ib stream for ClientSocket          
        inFromServer = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
       //Receive login message from telnet server
            modifedSentence = inFromServer.readLine();
        } catch (UnknownHostException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        }
                 //Update UI activity with login message
         MainActivity.this.runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                          textView.setText(modifedSentence);
                    }
                });   
        }
             }).start();
    }   
        });         
    }

   protected void onDestroy()
    {
        try {
            clientSocket.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}
