As someone else has already posted, the following will reproduce
the behaviour on my system:

  bash-2.02$ telnet localhost
  Trying ::1...
  Connected to localhost.
  Escape character is '^]'.
  Trying SRA secure login:
  User (deischen): ^C^C^C^C^C^C^C
  Password: 
  [ SRA login failed ]
  User (deischen): ^Z
  [1]+  Stopped                 telnet localhost
  bash-2.02$ kill -9 13164
  [1]+  Killed                  telnet localhost

Once you login and are connected, telnet can then again be escaped
with CTRL-].
