The current active user interface has had no activity (no key was pressed) for at least five minutes.

TThe active user interface has been released with the Release command.

The active interface connection is broken. This includes the call disconnect for a modem interface or the termination of the front panel emulation program on a locally attached PC (if the PC supports DTR) or the termination of the async terminal interface on a remote or locally attached terminal.
