Sets the new connection expression for this socket.
This expression is evaluated for listening TCP Socket when new connections arrive so you can call Socket.AcceptNewConnection.

Be aware that FileMaker Server does not allow the plugin to operate if no script is running. So if you use sockets there, make sure a script is running or paused while you expect an answer coming in.

In the expression the text $$ID$$ will be replaced when evaluated with the socket reference, so you can pass it to other functions if needed.
