    characters in urgent mode.

    o  Enabled - The local host sends an interrupt character in
       urgent mode, and the remote host immediately processes it.

    o  Disabled - TELNET sends the interrupt character in sequence
       with the other characters in the stream, and the remote host
       processes this character in the sequence received.
