|
|
.Cd device pt1 at scbus0 target 3 unit 0
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for a
|
|
.Tn SCSI
|
|
processor type device. These are usually scanners and other
|
|
devices using the
|
|
.Tn SCSI
|
|
link as a communication interface with device
|
|
specific commands embedded in the data stream.
|
|
.Pp
|
|
A
|
|
.Tn SCSI
|
|
adapter must be separately configured into the system
|
|
before this driver can be used.
|
|
.Pp
|
|
This device supports
|
|
.Xr read 2
|
|
and
|
|
.Xr write 2 ,
|
|
and the
|
|
.Xr ioctl 2
|

|
driver read and write timeout. The value returned is in seconds.
|
|
.It PTIOCSETTIMEOUT
|
|
This ioctl allows userland applications to set the current
