Hi,

I tried to create a serial connection between two computers with the
Serial Laplink HOWTO and it dosnt work. During booting I get the
following message:

Loading the saved-state of the serial devices...
Illegal UART type: undefined
/dev/ttyS0 at 0x3f8 (irq = 4) is a undefined
Illegal UART type: undefined
/dev/ttyS1 at 0x2f8 (irq = 2) is a undefined

Now I reserve the changes, but the message is the same.

My System
IBM Thinkpad T30
Ubuntu 5.0.4
Linux 2.6.10-5-386

The system should detect a serial device's UART at boot. Since it
doesn't my guess would be a winmodem, or relative thereof, is involved.
You can try setting the device file UART type with, e.g.,

setserial /dev/ttyS0 uart 16550A

(16550A is a common type) but I'm not at all optimistic it will work.

Are the serial ports enabled in the BIOS setup? In a laptop computer
they may be turned off to conserve battery power.

Yes the serial port is enabled.
