As of LCOS 10.80 actions can be manually triggered in the action table by simulating events. Certain connection events (e.g. establish, disconnect, volume budget event, etc.) can be triggered without the event actually occurring. This allows entries in the action table to be tested. The action of the action table to which the event applies is executed. All entries that match the event are always executed.
Under /Setup/WAN there is a new command-line action to do this: Manual-Action-Start.
