.SH DESCRIPTION
|
||
|
|
The \fBsasc\fP 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 behaviour of the asc scanner device. When \fBsasc\fP is
|
||
|
|
called with no option only the current settings are reported.
|
||
