@param command: a C{bytes} naming the command.
@param kw: arguments to the amp box.
@param requiresAnswer: a boolean.  Defaults to True.  If True, return a
Deferred which will fire when the other side responds to this command.
If False, return None and do not ask the other side for acknowledgement.
@return: a Deferred which fires the AmpBox that holds the response to
this command, or None, as specified by requiresAnswer.'
