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
