the tcp nodes are core nodes so are built in. - the source is here - [https://github.com/node-red/node-red/tree/master/packages/node\_modules/%40node-red/nodes/core/network](https://github.com/node-red/node-red/tree/master/packages/node_modules/%40node-red/nodes/core/network)

hi, tanks for answer.  
what this means? (line 323)  
if (node.doend === true) {  
end = true;  
if (client) { node.status({}); client.destroy(); }  
}  
node.doend ???

Hi @billyrudi,

When you activate (in the TCP-Out node's config screen) this checkbox:

Then you will see that your `node.doend` will become true:

So as soon as a input message arrives in the TCP-Out node, the client connection will be closed:
