Disconnection does not fire event until I try to send via the client

[EGirardi]

When I shut down the server side, my application using SuperSimpleTCP Client does not fire the disconnect event until i try to send something to the server - at that point it will fire the Disconnected event. How can i get the Disconnect event to fire as soon as the client gets disconnected ?

Interesting, how are you shutting down the server? Could you let me know what operating system, runtime/framework you are using?

I just tested using the test client and server apps, hitting CTRL-C even in the server (left side) caused the client (right side) to detect the disconnect immediately.

Seems like the embedded hardware does not respond to the keep-alive which causes the Client to terminate the connection - even though i can clearly see the client is connected in the embedded hardware side. Had to remove it from the code

May I ask what the device is?

[EGirardi]

It's a Crestron Control Processor - industrial type automation controller.

Got it. Will the hardware acknowledge a message that it cannot decipher? Or does it natively have a heartbeat function that you could take advantage of?

Its just a raw TCP connection my code will handle the heartbeat character. I did a simple test and it seems to work.
