Connection Keeper
by Gammadyne Software

  Connection Keeper prevents your Internet connection from appearing idle or inactive. It does this using almost no bandwidth or system resources. If a connection is lost, Connection Keeper can automatically dial back in. It can even automatically simulate a button click to close popup windows (such as those asking if you wish to remain connected). You can configure precisely how your line is kept active, and Connection Keeper's window can be minimized to the system tray.
