31.Nd SCSI processor type driver
32.Sh SYNOPSIS
33.Cd device pt0 at scbus?
34.Sh DESCRIPTION
35The
36.Nm
37driver provides support for a
38.Tn SCSI
39processor type device. These are usually scanners and other
40devices using the
41.Tn SCSI
42link as a communication interface with device
43specific commands embedded in the data stream.
44.Pp
45A
46.Tn SCSI
47adapter must be separately configured into the system
48before this driver can be used.
49.Pp
50This device only supports
51.Xr read 2
52and
53.Xr write 2 ,
54and the generic
55.Tn SCSI
56.Xr ioctl 2
57calls.
58The
59.Sq Li at scbus?
60is required in the config file for the configuration
61system to know this is a SCSI device and generate the appropriate
62tables.

72The
73.Nm
74driver has no

79commands. These are described in
