problems, Exporting tty terminal

[Jordi]

Now on the computer, whe export the terminal throught the serial port with this parameters in grub.conf:
serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
terminal --timeout=8 serial console
title Red Hat Linux (2.6.5-mm1-8kstacks)
root (hd0,0)
kernel /vmlinuz-2.6.5-mm1-8kstacks ro root=LABEL=/ console=tty1 console=ttyS0,115200
initrd /initrd-2.6.5-mm1-8kstacks.img


We need to use the same for knoppix and have tryed this:
title Knoppix ISO from HD (DVD 2005-06-0
root (hd0,0)
kernel /cluster-images/vmlinuz-2.6.12 2 ramdisk_size=100000 console=tty1 console=ttyS0,115200n8 myconf=/dev/sda3 lang=es noeject vga=normal BOOT_IMAGE=knoppix
initrd /cluster-images/minirt.gz

But after initrd starts to load the system, we get a blank screen (no more input) from the minicom remote console.
May I need remastering and recompiling the kernel included with knoppix for having support for exporting the terminal throught serial port? Or there is any problem because of the use of colours in knoppix boot? (note that we set vga=normal for avoiding framebuffer modes)


Lot Of thanks.
Jordi.

I have no braille device, but may do the trick?
