Description

exclon attempts to reserve your terminal for exclusive use. This means that any attempt to open your terminal, including through /dev/tty, will fail. excloff attempts to undo the effect of exclon(1).

Exception: root can still open your terminal. On most systems this means that talk(1) is not affected by exclon even though write(1) is.
