Returns OK or error.

### Description

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](SocketAcceptNewConnection.md).  
  
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.
