NAME

     uk -- SCSI user-level driver

SYNOPSIS

     uk* at scsibus? target ? lun ?

DESCRIPTION

     The uk driver provides support for a process to address devices on the SCSI bus for which there is no configured driver.

     A SCSI adapter must also be separately configured into the system before this driver makes sense.

KERNEL CONFIGURATION

     If a count is given, that number of uk devices will be configured into the NetBSD kernel.

IOCTLS

     The uk driver has no ioctls of its own but rather acts as a medium for the generic scsi(4) ioctls.  These are described in <sys/scsiio.h>.

FILES

     /dev/uk[0-255]  unknown SCSI devices.

DIAGNOSTICS

     All scsi(4) debug ioctls work on uk devices.

HISTORY

     The uk driver appeared in 386BSD 0.1.

NAME

     pt -- SCSI processor type driver

SYNOPSIS

     device pt

DESCRIPTION

     The pt driver provides support for a SCSI processor type device.  These are usually scanners and other devices using the SCSI link as a com-
     munication interface with device specific commands embedded in the data stream.

     A SCSI adapter must be separately configured into the system before this driver can be used.

     This device supports read(2) and write(2), and the ioctl(2) calls described below.

IOCTLS

     The following ioctl(2) calls are supported by the pt driver.  They are defined in the header file <sys/ptio.h>.

     PTIOCGETTIMEOUT  This ioctl allows userland applications to fetch the current pt driver read and write timeout.  The value returned is in
		      seconds.

     PTIOCSETTIMEOUT  This ioctl allows userland applications to set the current pt driver read and write timeouts.  The value should be in sec-
		      onds.

FILES

     /dev/ptN	 the Nth processor device.

HISTORY

     The pt driver appeared in FreeBSD 2.1.
