[Twisted-Python] Pulling the ethernet cable out

[gary clark]

Hey Alvin,

In the document link you provided the packets are being sent periodically every 2 hours for setTcpKeepAlive(1). I am assuming that
the a packet is sent straight away and then waits. At the moment I dont see the connection lost. The getTcpKeepAlive() is returning 1 indicating that keep alive is set.

Is there a way to change the delay?

Thanks,
Garyc
