exclon 1 user commands djbwares
exclon reserve tty for exclusive use
`exclon`

## 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.
