What really happens when closing a TCP/IP connection?

[davidwnypf]

Does anyone know the low level details of what the 'Close TCP/IP' vi does. I have been running a protocol analyzer and found that the vi does not notify the peer, client or server that the link is coming down. Usually a datagram is issued with the 'FIN' bit set. Any help would be appreciated.

Sorry...after further analysis I have found the Close TCP/IP vi executes exactly as it should. A TCP datagram with the FIN bit set is issued to properly request a close connection. Thank you.
