[Soekris] net4801 second serial port

[Jere Virta]

Hello,

I have few DS18S20 -temperature sensors, which are connect to a serial 
port with a simple adapter.
The temperatures are read using program called digitemp. This all works 
fine in another computer,
but when connect the adapter to a soekris board, the sensors can't be 
found or read.

So my question is, are there any special magic tricks needed in using 
the second serial port?
I'm using Linux on both system.
