.Sh NAME
.Nm pt
.Nd SCSI processor type driver
.Sh SYNOPSIS
.Cd device pt0
.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
calls described below.
.Sh IOCTLS
.Bl -tag -width 012345678901234
The following
.Xr ioctl 2
calls are supported by the
.Nm
driver.  They are defined in the header file
.Aq Pa sys/ptio.h .
.Pp
.It PTIOCGETTIMEOUT
This ioctl allows userland applications to fetch the current
.Nm
driver read and write timeout.  The value returned is in seconds.
.It PTIOCSETTIMEOUT
This ioctl allows userland applications to set the current
.Nm
driver read and write timeouts.  The value should be in seconds.

.Sh HISTORY
The
.Nm
driver appeared in 
.Fx 2.1 .
After prodding, add a BSD style copyright to those man pages I think I probably originally wrote. Also take my name OUT of the ddb man page.. I did NOT port it from mach. 1996-10-18 20:22:31 +00:00			`.\" Copyright (c) 1995`

Fix short timeout problems with the pt(4) driver: - increase the default timeout from 10 seconds to 60 seconds - add a new kernel option, SCSI_PT_DEFAULT_TIMEOUT, that lets users specify the default timeout for the pt driver to use - add two new ioctls, one to get the timeout for a given pt device, the other to set the timeout for a given pt device. The idea is that userland applications using the device can set the timeout to suit their purposes.
