Description
This command deletes a previously created socket and closes the connection (if connected).
•
If the socket is of TCP-type and a connection is established, the connection is terminated with the RST-
flag.
•
To gracefully terminate a TCP-connection, it is recommended to use the ‘Shutdown’-command (see be-
low) before deleting the socket, causing the connection to be closed with the FIN-flag instead.
