<P>Hi Ben,
<BR>
<P>I took a short look at the snapscan source. There are two things:
<BR>
1) I can find out from which time the scanning related values
<BR>
are set (not the guessed ones)
<BR>
2) it is possible (looks a bit like that) the the backend does
<BR>
not respond the complete lines in param.lines but the
<BR>
remainig lines until the end of the scan. That would be a big bug.
<BR>
<P>Can you find out about that, e.g. by adding a call to
<BR>
sane_get_parameters in xsane after sane_read ?!
<BR>
<P>Bye
<BR>
Oliver
