How to set the console output

This problem I found when the server has several output terminal; KVM console (VGA output) and serial console.

How to check what primary output in-use:- 

1. No any output stream on the terminal

2. Check via command line in shell mode

    shell> conconfig

This means primary output terminal

To change the primary output:- 

    shell> conconfig 2 primary

Means change terminal 2 as primary instead.

Ps. I do not have any pictures in my hands now. I will add some pictures later (when I found one :P)
