Test application to read the 1-Wire Weather Station.
The weather station consists of the following devices
on the trunk of the MicroLAN (1-Wire Net):
   DS1820 - temperature measurement
   DS2423 - counter for reading wind speed (page 15)
   DS2407 - switch to isolate 8 DS2401's for wind 
            direction on channel B.

This application uses either the 'general' or 'userial'
1-Wire Net implementations.

Required on the command line is the 1-Wire Net port name:

    example: "COM1"      (Win32 DS2480)
             "/dev/cua0" (Linux DS2480)
             "1"         (Win32 TMEX)
