// SUBROUTINE - FindWeather

// network and returns the serial numbers for the weather station. If
// it is the new weather station then it is not going to have an DS2401s.
//
// 'ds1820' - This will be the serial number for the DS1820 in the station
// 'ds2423' - This will be the serial number for the DS2423 in the station
// 'dsdir' - This will either be the DS2450 or the DS2406 serial num.
// 'ds2401' - This will be the list of DS2401s if the old weather station.
//
// Returns: TRUE if a weather station is found and the listing of the
// devices file is found or made. FALSE if a weather station
// is not found or the device file is not found or can not be made.
