.Sh DESCRIPTION
The
.Nm
utility provides shell level access to the ioctl
requests served by the handy scanner device driver asc. Please see
asc(4) for the exact meaning of the requests. Generally they modify
the output and behavior of the asc scanner device. When \fBsasc\fP is
called with no option only the current settings are reported.

for the exact meaning of the requests. Generally they modify
the output and behavior of the asc scanner device. When
.Nm
is called with no option only the current settings are reported.
.Sh OPTIONS
The following options are available:
.Bl -tag -width indent
.It Fl s Bq ASC_SRESSW
Set the scanner with the values of the resolution selector switch.
.TP
\fB-q\fP
.It Fl 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.
.TP
\fB-f\fP \fIfile\fP
.It Fl f Ar 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.
.TP
\fB-r\fP \fIresolution\fP [ASC_SRES]
.It Fl r Ar resolution Bq ASC_SRES
Set the resolution in dpi.
.TP
\fB-w\fP \fIwidth\fP [ASC_SWIDHT]
.It Fl w Ar width Bq ASC_SWIDHT
Set the width of the bitmap in pixels.
.TP
\fB-h\fP \fIheight\fP [ASC_SHEIGHT]
.It Fl h Ar height Bq ASC_SHEIGHT
Set the height of the bitmap in lines of pixels.
.TP
\fB-b\fP \fIlen\fP [ASC_SBLEN]
Set the internal dma buffer to be \fIlen\fP lines in size.
.TP
\fB-t\fP \fItimeout\fP [ASC_SBTIME]
.It Fl b Ar len Bq ASC_SBLEN
Set the internal dma buffer to be
.Ar len
lines in size.
.It Fl t Ar timeout Bq ASC_SBTIME
Set the timeout time for reading one dma buffer.
