+.SH DESCRIPTION
+The \fBsgsc\fP 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 \fBsgsc\fP is
+called with no option only the current settings are reported.
+.SH OPTIONS
+.TP 3
+\fB-s\fP [GSC_SRESSW]
+Set the scanner with the values of the resolution selector switch.
+.TP
+\fB-q\fP
+Operate in quiet mode, i.e. do not report any of the current setings.
+Normally the parameters are shown after the modifications have been
+performed.
+.TP
+\fB-f\fP \fIfile\fP
+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.
+.TP
+\fB-r\fP \fIresolution\fP [GSC_SRES]
+Set the resolution in dpi.
+.TP
+\fB-w\fP \fIwidth\fP [GSC_SWIDHT]
+Set the width of the bitmap in pixels.
+.TP
+\fB-h\fP \fIheight\fP [GSC_SHEIGHT]
+Set the height of the bitmap in lines of pixels.
+.TP
+\fB-b\fP \fIlen\fP [GSC_SBLEN]
+Set the internal dma buffer to be \fIlen\fP lines in size.
+.TP
+\fB-t\fP \fItimeout\fP [GSC_SBTIME]
+Set the timeout time for reading one dma buffer.
+.SH FILES
