<para>
If the tty service has been configured and is available for the
container specified as parameter, this command will launch a
console allowing to log on the container.
</para>
<para>
The available tty are free slots taken by this command. That
means if the container has four ttys available and the command
has been launched four times each taking a different tty, the
fifth command will fail because no console will be available.
</para>
<para>
The command will connect to a tty. If the connection is lost or
broken, the command can be launched again and regain the tty at
the state it was before the disconnection.
</para>
<para>
A <replaceable>ttynum</replaceable> of 0 may be given to attach
to the container's /dev/console instead of its
dev/tty<<replaceable>ttynum</replaceable>>.
</para>
<para>
A keyboard escape sequence may be used to disconnect from the tty
and quit lxc-console. The default escape sequence is <Ctrl+a q>.
