<EM>&gt; Hello Nicholas,
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; it seems that the scanner does not respond to some of the very first
</EM><BR>
<EM>&gt; inquire commands. It recognized as an HP scanner because otherwise it
</EM><BR>
<EM>&gt; would have failed earlier.
</EM><BR>
<EM>&gt; Maybe it is a timing problem.
</EM><BR>
<P>This doesn't seem quite right coz...

<P>Here it appears to test for the version, and gets s257E instead of

s257d, and then...
