Would you like show me an simple example about this? I wrote one, but
it dosn't work.

__sender = None

class p(Protocol):
    def connectionMade(self):
        print "Connecttion make"

    def sendMessage(self):
        self.transport.write("some message")

    def connectionLost(self, reason):
        print "Lost, reason", reason

def sendCmd(addr, port, cmd, task, options = ""):
    """Send Cmd to
    global __sender

    __sender.connectTCP(addr, port).addCallback(send,\
            cmd, task, options)

def send(p,cmd, task, options):
    print "send"
    return p

def finishConnection(p):
    print "lostConnection"

def initSendCommand():
    global __sender
    if not __sender:
        __sender = ClientCreator(reactor, p)

if __name__ == "__main__":
    def testSendMessage():
        sendCmd("localhost", 8009, "test send")

    thread.start_new_thread(testSendMessage, ())
