Suggestion

When I am using this module to setup the server, I found I have two choice:

1. request_will_echo
   connect the server through putty, Input will not display when type in the command until press enter
2. request_wont_echo
   Input will display when typing, but because the telnet echo is False, the command been input will be replaced by the information server returned.

would you consider add another choice like this :
def request_will_echo(self): self._iac_wont(ECHO) self._note_reply_pending(ECHO, True) self.telnet_echo = True
