[Jochen Eisinger]
<BR>
<EM>&gt; I've written a nice little interface for the Mustek parallel port
</EM><BR>
<EM>&gt; chipset A4S2...
</EM><BR>
<P>I'm impressed. I expected you to brush up the sanei_pio API to match
<BR>
your needs, not make a completely new and generic chipset API. :-)
<BR>
<P><EM>&gt; sadly, this isn't a working backend, just the hardware functions to
</EM><BR>
<EM>&gt; access the registers of the scanner.
</EM><BR>
<P>Is this chipset API enough for the backend to only implement the
<BR>
high-level functionallity, and not require any hw access?
<BR>
<P><EM>&gt; There is already a backend for this chipset, which implements all
</EM><BR>
<EM>&gt; these functions. However, Petter Reinholdtsen said, it would be
</EM><BR>
<EM>&gt; better, if the hardware handling code would be in a SANE interface
</EM><BR>
<EM>&gt; (like sanei_pio, sanei_ab306).
</EM><BR>
<P>After reading thru the source, it seems like a few of the functions
<BR>
might be used to improve the pio API. It must be possible to make a
<BR>
parport API that works on all platforms. Are the _epp functions
<BR>
implementing the 'enhanced parport' mode? I've been reading about the
<BR>
the Linux parport kernel API, and noticed support for epp, ecp and
<BR>
nibble mode in this API. Would a sanei parport API with support for
<BR>
such modes make it easier to support parport scanners?
<BR>
<P>Happy hacking,
<BR>
