How to disconnect from Internet?

[-anachesa-]

Hello,
does anybody know how could I break an Internet connection programmatically? Closing sockets does not solve the problem of course. I guess that to break up a connection I have to do something with RComm and related stuff, am I right? Any code examples would be appreciated!

If all socket connections are closed (e.g. with Shutdown()) an Internet connection should be automatically terminated.
