I've got a simple little chat server set up that people can telnet into. The code is as follows:

----------

from twisted.internet import reactor
from twisted.internet.protocol import ServerFactory
from twisted.protocols.basic import LineOnlyReceiver
import threading

class ChatProtocol(LineOnlyReceiver):

    name = ""

    def getName(self):
        if self.name!="":
            return self.name
        return self.transport.getPeer().host

    def connectionMade(self):
        print "New connection from "+self.getName()
        self.sendLine("Welcome to the chat.\r\n/quit to quit.")
        self.factory.sendMessageToAllClients(self.getName()+" joined the chat.")
        self.factory.clientProtocols.append(self)

    def connectionLost(self, reason):
        print "Lost connection from "+self.getName()
        self.factory.clientProtocols.remove(self)
        self.factory.sendMessageToAllClients(self.getName()+" disconnected.")

    def lineReceived(self, line):
        if line=="/quit":
            self.transport.loseConnection()
        else:
            self.factory.sendMessageToAllClients(self.getName()+": "+line)

    def sendLine(self, line):
        self.transport.write(line+"\r\n")

class ChatProtocolFactory(ServerFactory):

    protocol = ChatProtocol

    def __init__(self):
        self.clientProtocols = []

    def sendMessageToAllClients(self, mesg):
        for client in self.clientProtocols:
            client.sendLine(mesg)

def Test():
    global test
    factory.sendMessageToAllClients('Hey.')
    test = threading.Timer(1.0, Test)
    test.start()
test = threading.Timer(1.0, Test)
test.start()

print "Starting Server"
factory = ChatProtocolFactory()
reactor.listenTCP(3009, factory)
reactor.run()

----------

The problem is that last def, "def Test()". It should send the line "Hey." to all connected users every second. It does that - however, the message only sends through if the client is typing or has entered a line. So, if a client is idle for 30 seconds, then starts typing, he will receive "Hey." 30 times in a row - one for each second he was idle.

Is there any way to get this to send the message and have it show up for a client even when they're idle?
