>Description:

    Recent changes to telnet prevent the use of the escape character
    during authentification.

>How-To-Repeat:

    bash-2.04$ telnet localhost
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.
    Trying SRA secure login:
    User (pherman): ^]^]^]^]^]^]^]^]^]^]^Z
    [1]+  Stopped		      telnet localhost
    bash-2.04$ kill %1
    [1]+  Terminated	      telnet localhost
    bash-2.04$ telnet -X SRA localhost
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.
    login:
    telnet> cl
    Connection closed.
    bash-2.04$ telnet -K localhost
    Trying 127.0.0.1...
