    One of my Geiger counters simply sends text data strings once every 
second.  It's knowing what each chunk of data represents.  The 
documentation that came with mine gave the data format, so it was easy to 
capture the data on a serial interface, parse it, and display the data in 
a formatted screen.  All done with a Bash script.  Could also make it web 
accessible, some day.  Too many 'projects' and never enough time...
