This could sure be done with National Instruments LabView. Although  
in the latest version this is a quite expensive program, there was a  
free (older) version on a DVD that came with the German computer mag  
c't a few months ago. The DVD contains only the Windows version, Mac  
(OS 9) and Linux versions can be downloaded here:
