At first, you need to enable serial ports in your BIOS and wire them up to the case front (if they aren’t allready).
Make sure you have the following in your /boot/grub/menu.lst:
serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
terminal --timeout=10 serial console
# kopt=root= ro console=tty0 console=ttyS0,115200n8
Check that “ttyS0″ is in /etc/securetty, remove /etc/ioctl.save, if its there.
Last change goes to /etc/inittab, add there:
T0:23:respawn:/sbin/getty -L ttyS0 115200 vt100
Now you can use a terminal program like minicom with 115200 baud, 8n1 and no flow control set.
Have fun and much luck on recovering your machine!
Don´t ask how, but we got some units to europe.
The first thing we does, was to install openwrt and to try debridge the switch to have multiple interfaces instead. We was able to remove ports from the switch, but cant create additional working vlans like on WRT54G. So at this point its useless for our purpose. But we will start exploring as son as possible we have a running serial console.
Today my goal was to get an AVM Fritz!Card running to send SMS via yaps.
Since on the old system is running kernel 2.4.x at the time of setup the only option was to use the capi driver and some hacks with hylafax to get all running. I don’t wonna look deeper into the old setup, to prevent to get mad. Anyways … an other setup was a faxserver. This was implemented also with the capi driver and capisuite.
So I was going straight forward and installed the capi driver on the known way.

Since I started playing around with vserver there is the problem left restricting the capacity of the disk usage of the guests.
One solution may be to use one partition per vserver guest. But what to do if there is more (or less) space needed on the systems? Shutting them down and copying to bigger or smaller partition may not acceptable in any cases.
An other path can be LVM and (online-)resizeable filesystems.
