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.
SEE ALSO cam(4)HISTORY
The pt driver appeared in FreeBSD 2.1.

Hi All,
I have been trying to use the option -S in sudo for quite some time now but have not been successful. I get the error "Inappropriate ioctl for device" most of the time. Can anyone please tell me how to use this option to pass the password.
Your help is appreciated.
Thanks,

Hi
I'm looking for a simple and nice sample for writing a device driver in SCO OpenServer 5.0.7. I'm asked to write a device driver for some usb printer.
