Smthng like that.
Yes, I'm trying to direct console output to ttyS2 and to the VGA card at the
same time.
I don't care if I have to direct it only to ttyS2, but I need to have the
input from
the PS/2 keyboard. When I use the line
s2:2345:respawn ....
in inittab, it sends a login prompt to the display connected to ttyS2,
different console than
that on tty0, therefore, obtaining the keyboard input from PS/2 only for
tty0.
If I use the command append="console=ttyS2,9600 ...." in lilo.conf it
happens what I explained
in the first mail. If U want to, I can send you a mail with the kernel and
init messages I got
connecting another serial port to ttyS2 and saving the data.
I've seen everywhere it should be as simple as redirecting the output with
the "console" command.
But it doesn't continue working alright after the Welcome message. ¿?
