Hi,
I would like to understand how the shell is tied to the console port. When
an user connects a terminal
to the system via console port, a shell is started and tied to the console
port (/dev/console ?).
Can some someone explain how this whole process works?. It would be great if
you can point me
the source code and/or the any documents.

Thanks
Kailas
