code: def sendto(self, data, addr, flags=0):
          
          return self.llc.sendto(self._tco, data, addr, flags)
docs: Send data to the socket. The socket should not be connected
          to a remote socket, since the destination socket is specified
          by addr. Returns a boolean value that indicates success
          or failure. Failure to send is generally an indication that
          the socket was closed.
