Telneting and J Text Area

Question

(I have the same Issue!! Please Help!)
Hello,
My program is able to telnet into a remote machine and the text is displayed using JTextArea. However whin I do a 'dir' on the host
my JtextArea (Using setText(String)) appears to be getting the data yet no other data is displayed.
Any sugesstions? (Please see the 'tagged' code below)
Thanks

/* Constructor */
public RemoteConnection(String Host, int TelnetPort)
try
{ /* Create a new Socket and call the pipe streams */
/* This does not output data to the window */
socket = new Socket(Host, TelnetPort);
/* This works...I can create a terminal emulator*/
//socket = new Socket("time.gov", 13);
new InputPipe(socket.getOutputStream()).start();
new OutputPipe(socket).start();
catch(IOException e)
txtTelnetWindow.setText("");
txtTelnetWindow.setText("Error Could not connect to host: "+Host);
return;
}/* end Constructor */

Reshy,
You shouldn't post the same question on 3 different forums. Please refer to my answer on 'Advanced Language Topics' and if that works I want these Dukes as well ;).
