I have a scanner (for fingerprints) which connects<br>
to the parallel port. I want to develop a SANE<br>
interface for this beast but the company has not<br>
been forthcoming with the specifications.<br>
What is the best way to proceed with reverse <br>
engineering?<br>
<p>
The device can be run under NT and I see no evidence<br>
of a driver (no *.sys file). How similar are the<br>
NT and Linux lp drivers?<br>
Should/can I put some kind of sniffer on the port?<br>
<p>
Is there documentation on how to proceed with a<br>
reverse engineering job?<br>
<p>
Thanks,<br>
Fred<br>
