pt — SCSI
processor type driver
pt driver provides support for a SCSI
processor type device. These are usually scanners and other devices using
the SCSI link as a communication 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.
The following ioctl(2) calls are supported by
pt driver. They are defined in the header file
- This ioctl allows userland applications to fetch the current
ptdriver read and write timeout. The value returned is in seconds.
- This ioctl allows userland applications to set the current
ptdriver read and write timeouts. The value should be in seconds.
- the Nth processor device.
