Break a telnet connection

[Ash maker]

Hello,
In a telnet connection I have sent a break request to terminate the connection. Here is my code

	OutputStream getOutputStream ust =();
...
        ust.write(TelnetCommand.getCommand(TelnetCommand.BREAK));
        ust.flush();
...

Though I have done it, it is not working. Any other solution than this will be appreciated. Thanks in advance.

Hello,
Which library do you use? What's wrong? What is the code producing the error? So many questions whose answers are important to help. I think you are not precise with the question. What exactly do you want, I mean how you want your program to work. And I think this is just the part of your code. Post the full or the part of the code which contains the logic of the code.

Hello,
Even I am trying something like this. I use the library commons-net jakarta, actually I'm not getting an error, the server-cons with which I should return match a specific answer, but it returns me nothing. It works in command line via a telnet client.
This is what I test

PrintStream str = new PrintStream(getOutputStream());
..
   str.System.out.println(TelnetCommand.getCommand(TelnetCommand.BREAK));
   str.flush();
..

And even I test this

usr.write(new byte[]{(byte)TelnetCommand.IAC, (byte)TelnetCommand.BREAK});
 usr.flush();

Hello,
By-cons, If I use the method println in class PrintStream are not force us to the CR and LF bytes?
Here is the code.

PrintStream prstr = new PrintStream(getOutputStream());

prstr.System.out.println({ (byte) TelnetCommand.IAC, (byte) TelnetCommand.BREAK });
prstr.flush();

Do you have any idea about this.

Hello,
Is it worth while to send the byte BREAK? Try not, his behavior seems a little suspect. In fact, sends a command, it finishes by CR LF (or use System.out.println) and looks. I think it will better. Finally, after a short discussion, the CR LF may be better than System.out.println (), because in my memory System.out.println () retrieves the standard way to the platform to go on line (with windows is CR LF with Linux: only LF and MacOS with: CR, although I may be wrong by inverting for Linux & MacOS). And a Telnet server application explicitly CR LF.

Hello,
This is what I have done in my code till now. I guess, if some people are interested then they will solve this problem. The code is here

...
    static Final byte[] cmdbr = { (byte) TelnetCommand.IAC, (byte) TelnetCommand.BREAK };
...
 
    Final void _sendBRK()
    throws IOException, IllegalArgumentException
    {
        otpt.write(cmdbr);
        otpt.flush();
    }
