I'm using INDY 9 components for a TCP server application.  Is there a way to detect when a client disconnects?  Each of the way to test for disconnect that I've found only work after both the client and the server have disconnected.  Using netstat, the connection state is in CLOSE_WAIT when the client disconnects and until the server also disconnects.  Is there a way to programatically check for this CLOSE_WAIT state?

Thanks, Paul Mac
