<P>
Oliver,
<BR>
<P>When scanning the Kodak Gray Scale target, I've seen where its darker on top
<BR>
and lighter on the bottom of the gray scale target. I get inconsistent scan.
<BR>
Do you know if the lamp maintain it's brightness consistently for all scans?
<BR>
&nbsp;&nbsp;Does this build fix this problem?
<BR>
<P>Thanks,
<BR>
Kym

</EM><BR>
<EM>&gt;Date: Sun, 13 Aug 2000 17:19:23 +0200
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt;Hi,
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt;sane-umax-1.0.3-build-22 is available on my homepage.
</EM><BR>
<EM>&gt;The build-21 is included into sane-1.0.3.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt;I decided not to included build-22 into sane-1.0.3 because
</EM><BR>
<EM>&gt;there was not enough time to test the scsi-command-queueing routines
</EM><BR>
<EM>&gt;before sane-1.0.3-code-freeze has been defined.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt;On my system these routines work stable.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt;The lamp status routines are dfined for UMAX Astra 4000
</EM><BR>
<EM>&gt;it looks like they do not work with Astra 2200/1220S/1200S
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt;Here are the other news:
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; * replaced fgets() by sanei_config_read()
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; * added command queueing for scsi read commands
</EM><BR>
<EM>&gt; - removed WAIT_SCANNER scsi command call after read command
</EM><BR>
<EM>&gt; - the additional buffers are allocated in the reader process
</EM><BR>
<EM>&gt; - the number of buffers can be defined in umax.conf
</EM><BR>
<EM>&gt; with option scsi-maxqueue [1..8] default:2
</EM><BR>
<EM>&gt; (did some tests with Supervista S12 and PowerLook III
</EM><BR>
<EM>&gt; on the same scsi controller (ncr53c810):
</EM><BR>
<EM>&gt; command queueing works, it is possible to start
</EM><BR>
<EM>&gt; both scanners at the same time. The scanner with the
</EM><BR>
<EM>&gt; higher scsi-ID (=priority) does scan without stops,
</EM><BR>
<EM>&gt; the other scanner has to wait long time between the
</EM><BR>
<EM>&gt; scsi-read commands, it also is possible to give
</EM><BR>
<EM>&gt; bothe scanners different scsi command queueing depth).
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; * prepared replacement of pipe by sanei_ipc_* routines
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; * added routines umax_get_lamp_status and umax_set_lamp_status
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; * updated inquiry output (new bits from powerlook scsi protocol 1.0
</EM><BR>
<EM>&gt;X101)
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; * added new (powerlook scsi protocol 1.0 X101) window descriptor block
</EM><BR>
<EM>&gt;entries to umax-scsidef.h
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; * added button protocol (3 buttons, from powerlook scsi protocol 1.0
</EM><BR>
<EM>&gt;X101)
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; * added button &quot;lamp off&quot; to turn off scanner lamp
</EM><BR>
<EM>&gt; (this option may be remoeved again in later version, may be
</EM><BR>
<EM>&gt; it will be replaced by an autmatic lamp turn off function)
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; * added options to umax.conf
</EM><BR>
<EM>&gt; lamp-off-at-exit [01] default:0
</EM><BR>
<EM>&gt; lamp-off-time [10..720] (in minutes) default:30
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; * if lamp_off_at_exit == 1 and lamp_control_available == 1
</EM><BR>
<EM>&gt; the scanner lamp is turned off in sane_close
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt;
