[Twisted-Python] The opposite function of reactor.listenTCP()

[hz hanks]

Hi All,

I have a server listen to two ports and run as follows:

       reactor.listenTCP(PORT1, file_trans_service.getFileTransCtrlServFactory()
       reactor.listenTCP(PORT2, file_trans_service.getFileTransCtrlServFactory()
       reactor.run()

Now I want to close the function of PORT1, but I just don't find the
opposite function of reactor.listenTCP(). Anyone can give me a hand?

Best,
Hanks
