The ctrl-] keystroke doesn't get sent down the wire, it's commands to
the _local_ telnet. For instance, if your session has stalled, you can
enter "^]close" to immediately disconnect. There won't be a direct way
to drop to "command mode" inside telnetlib, but you can do similar
actions with methods on the connection object (in that instance,
close() will do the job).
