+the virtual console console devices.
+If no arguments are specified
+(or only the
+.Ar list
+argument),
+the current console settings are shown.
+.Pp
+There are two types of logical consoles; a high level console which
+is represented by /dev/console, and a low level console.
+The low level console is used for kernel printfs and debugger support,
+while the high level console is used by user programs like syslog.
+Multiple device support is implemented only for the low level console,
+the high level console is set to the first device in the console list.
+.Pp
+Multiple console support may be invoked by passing the kernel the
+-D
+flag from the boot loader, or by using
+.Nm
+to change the list of console devices after the system has booted.
+.Pp

+devices; the first device is used for the high level console.
