### Result

Returns OK or error message.

### Description

Sets the new connection handler for this socket.  
This script is called 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.  
  
The script parameter is the ID of the socket. You can associate additional values with [Socket.SetTag](SocketSetTag.md) function to the socket and use them in the script triggered.  
  
  
With plugin version 6.0 or newer the script name can be a script ID number. In that case the plugin queries the script name for the given script ID. This allows to call scripts by ID and avoid problems if scripts are later renamed.  
  
Notice: FileMaker 19.2 adds a fmplugin extended privileges. If you have such an extended privileges to allow the plugin to trigger scripts, you need to grant permissions for it. If such a privilege is not defined, the plugin is allowed to trigger scripts. See FileMaker product documentation for details.
