Hello!<br>
I found some information on a project for making a driver for the <br>
portable mp3 player made by Diamond (Rio PMP300) which uses a parallel<br>
port for transferring music files. The interesting fact is that it is a <br>
proprietary protocol interface so the programmers had to guess <br>
the protocol in a unusual way.<br>
I am including some of the documentation of the Rio driver for Linux.<br>
I wonder if the Sane developers are using a similar approach when they<br>
are facing a proprietary parallel port Scanner and the manufacturers<br>
refuse to disclose information about the protocol. :-)<br>
<p>
bye,<br>
