Hi Jay,
It will be useful every different combination of scanning, but trying
to understand button polls is a good way to start coding and testing.
That's the first thing the hp4200 test program could do, and also for
the IBM Ideascan (http://ideascan.sourceforge.net)
To understand (only) the scanning protocol, it will be better to
exclude the button polls from the log file.
It will be nice to publish all those log files in the WWW, so people
interested in those files, or just curious people, can view/download
them. Maybe opening a sourceforge project could be the easier way.
Please, don't forget to annotate the scanning parameters used to
generate those log files! (and save the scanned image)
Cheers,
Adrian Perez Jorge
