How to clear a Xyplex port

It's possible for a terminal server port to become orphaned. A program using the terminal server might've crashed without the terminal server finding out and it will refuse to let anyone else log in. You can clear a Xyplex port with the following procedure:
  1. From a terminal window, telnet to the terminal server:

    2. % telnet monts1 2000
    Trying 192.41.211.121...
    Connected to monts1.apo.nmsu.edu.
    Escape character is '^]'.
     
  2. Hit the Enter key and you'll get a # prompt:

    3. #
     
  3. At the prompt, type the word access followed by the Enter key. Your typing will not be echoed.

    4. #
     

            Welcome to the Xyplex Terminal Server.
     
     

    Enter username>
     

  4. Type anything as a user name.

    5. Enter username> au
    Xyplex>
     
  5. Type the show users command:

    6. Xyplex> show users

      2   (Remote)   Available      (Remote Connect)
      3   (Remote)   Connected      (Remote Connect)
      4   (Remote)   Available      (Remote Connect)
      5   (Remote)   Available      (Remote Connect)
      6   (Remote)   Available      (Remote Connect)
      7   (Remote)   Available      (Remote Connect)
      8   (Remote)   Available      (Remote Connect)
     

    Xyplex>
     

  6. In this case, we see that port 3, the 20-inch telescope control port, is connected. Port 0 (with the Executing Cmd) is you. To clear the connection to port 3, you'll need to become a privileged user:

    7. Xyplex> set priv
    Password>
    Xyplex>>
     
  7. Now clear the port:

    8. Xyplex>> logout port 3
    Xyplex>>
     
  8. And logout from the terminal server:

    9. Xyplex>> lo
     

    Connection closed by foreign host.server X0EBE66 at 13 Apr 1999  10:38:49
