[Tammy Liang]

How did xconsole, lan console or secure web console get the message send to /dev/console and display it?

Thanks for any help

NAME
console, systty, syscon - system console interface

DESCRIPTION
/dev/console provides a termio interface to the device configured as
the system console. The init(1M) man page discusses the uses of
/dev/systty and /dev/syscon.

Output data normally sent to the console, either through /dev/console
or generated by a kernel printf, may be redirected to another terminal
or pseudo-terminal device through the TIOCCONS ioctl(). See termio(7)
for details.
