This is a simple Program for reading the PC Funkuhr (PCF) Modul
from Conrad Elektronik. The Modul is connected to the parallel 
port and look like a printer cable with a white box in it.
The Time and Date is shown in a LC-Display.

When you run the program without a parameter, then a portlist is scanned
for the modul. If it is found then the time is set and the port is printed.
When you know the port where the modul is connected, then you can give the
port a parameter (e.g. pcf 0x278). This is the prefered method to avoid 
scanning wrong ports.

Some information from feedbacks I got:
- you should configure the parellelport to unidirectional
- with a printer connected to the cable, it may not work
- on fast PCs (200 MHz Pentium and above), you may have to adjust
  the value for FAKTOR. Try values between 240 and 260.
- you have to run it with root privileges

Usually the program should be started during the boot. 
  
Have a good time
