Re: question about /dev/console and /dev/tty

[Tomko <tomko@avantwave.com>]

Hi,
Thank you very much for the reply, but i would like to ask some more.

1. it seems we can choose which device we want for console output by 
typing this on kernel command line:
console = device , options
if i type  "console = ttyS1 " is that means kernel will internally link 
/dev/console to /dev/ttyS1 , and when i do any operation to /dev/console 
, it is the same as i do to /dev/ttyS1 ?

2 . what means foreground virtual console as tty0 is representing ?

Regards,
TOM
