     sgsc -- set the options of the gsc scanner device

SYNOPSIS    [Toc]    [Back]

     sgsc [-sq] [-b len] [-f file] [-h height] [-r resolution] [-t timeout]
	  [-w width]

DESCRIPTION    [Toc]    [Back]

     The sgsc utility provides shell level access to the ioctl requests served
     by the handy scanner device driver gsc.  Please see gsc(4) for the exact
     meaning of the requests.  Generally they modify the output and behaviour
     of the gsc scanner device.  When sgsc is called with no option only the
     current settings are reported.

     The following options are available:

     -s [GSC_SRESSW]
	     Set the scanner with the values of the resolution selector
	     switch.

     -q      Operate in quiet mode, i.e. do not report any of the current settings.
  Normally the parameters are shown after the modifications
	     have been performed.

     -f file
	     Operate on a different scanner device node given by filename.
	     Note that even though there may exist more than one node of scanner
 device several of them will refer the same device unit.  The
	     modifications are performed od the unit regardless of the device
	     node by which it is accessed.

     -r resolution [GSC_SRES]
	     Set the resolution in dpi.

     -w width [GSC_SWIDHT]
	     Set the width of the bitmap in pixels.

     -h height [GSC_SHEIGHT]
	     Set the height of the bitmap in lines of pixels.

     -b len [GSC_SBLEN]
	     Set the internal dma buffer to be len lines in size.

     -t timeout [GSC_SBTIME]
	     Set the timeout time for reading one dma buffer.
