Hello,
<BR>
<P>I'm using a parport scanner and a printer under Linux and at the moment they
<BR>
function quite fine.
<BR>
The only thing that bothers me is that when I want to use the scanner, and
<BR>
after that the printer, then I have to use the commands rmmod and
<BR>
insmod/modprobe.
<BR>
At least, as far as I know the printer modules parport, parport_pc and lp, and
<BR>
the scanner modules ppscsi and onscsi (or whatever) cannot be loaded at the same
<BR>
time.
<BR>
<P>I wonder if it is possible to have them loaded at the same time, by using
<BR>
parameters. I do not know how to set these, but maybe someone does.
<BR>
<P>Under M$ it is possible to use a scanner and a printer not really at the same
<BR>
time, but one right after the other, as long as you don't really use them at
<BR>
the same time. I mean scanning and printing at the same time, then one process
<BR>
goes wrong. Maybe then the M$&quot;modules&quot; are loaded and unloaded dynamically, but
<BR>
I don't guess so.
<BR>
<P>Under M$ this works automatically, but if not then it is possible (with my
<BR>
Microtek scanner and driver) to add parameters.
<BR>
The next is from a readme file:
<BR>
<P>&nbsp;&nbsp;ASPI Manager is needed if you want to use any SCSI device. The following are
<BR>
&nbsp;&nbsp;the command line options for the ASPI Manager. Th
<BR>
&nbsp;&nbsp;ese options should be used ONLY if the ASPI Manager fails to detect the
<BR>
&nbsp;&nbsp;hardware.
<BR>
<P>&nbsp;&nbsp;/V - Enables slow mode
<BR>
&nbsp;&nbsp;/SF=1..30 - Slows down the access by forcing a slow factor ranging from 1
<BR>
&nbsp;&nbsp;to 30
<BR>
&nbsp;&nbsp;/U - Forces uni-directional mode, it is the slowest mode of
<BR>
&nbsp;&nbsp;operation.
<BR>
&nbsp;&nbsp;/E - Slows down EPP access. Use this option only if you are sure
<BR>
&nbsp;&nbsp;that your printer port is an Enhanced Parallel Port. On other port types,
<BR>
&nbsp;&nbsp;this option has no effect.
<BR>
&nbsp;&nbsp;/P - Pauses if the driver fails to install. The DOS boot process
<BR>
&nbsp;&nbsp;will display an error message and wait for the user to press a key before
<BR>
&nbsp;&nbsp;continuing.
<BR>
&nbsp;&nbsp;/I=5 - Makes the scanner use irq 5, while the printer and the
<BR>
&nbsp;&nbsp;lpt-port are still using irq 7.
<BR>
<P>I wonder if something like this is also possible under Linux.
<BR>
Ofcourse it might be possible to have these modules loaded at the same time in
<BR>
another way.
<BR>
<P>For me this would make it more easy to use.
