Dallas Semiconductor Components Serial Numbers

I'm currently working with a 1-wire weather station and am using a pic 16F648A to read data from it. The system contains 3 different Dallas Semiconductor components which each have 64-bit individual addresses. I was wondering if anyone had a program to find the serial numbers of these components.

Here's one example: http://www.rentron.com/PicBasic/PBP1-wire.htm

The datasheets usually talk about s/n discovery.
