This is a HP SCSI scanner driver which uses the FreeBSD 'pt' (Processor
|
|
Type) driver. It has been tested on the HP ScanJet 3C and 4A, and was
|
|
written for the HP ScanJet IIcx, so I suspect it will work with all newer
|
|
HP scanners without modifications.
|
|
|
|
To install the driver you must add a line to your kernel config file
|
|
like the following:
|
|
# HP Scanner
|
|
device pt0 at scbus?
|
|
|
|
Re-configure, build, and install the new kernel. On bootup you should
|
|
seem something similar to this which shows your scanner is attached:
|
|
(ncr0:5:0): "HP C2520A 3503" type 3 fixed SCSI 2
|
|
pt0(ncr0:5:0): Processor
|
|
|
|
Next, you'll want to make a link from /dev/pt0 to /dev/scanner for the
|
|
driver software.
|
|
|
|
# cd /dev
|
|
# ln -s pto0 scanner
|
|
|
|
At this point, you should be able to run the scanner program and see
|
|
results.

This is (a very early version of) a SCSI driver for the HP ScanJet range
|
|
of scanners and a corresponding graphical user interface.
|
|
|
|
The HP scanners (or at least some of them) are SCSI devices, but do
|
|
not implement the SCSI scanner interface. Instead they act as SCSI
|
|
processor devices. They use the SCSI send and receive commands to
|
|
transfer (hard as it is to believe) escape sequences.
|
|
|
|
The file scsi.c implements the SCSI send and receive commands in user
|
|
mode, using the *BSD "uk" (unknown device) driver. The uk driver is
|
|
somewhat flaky, rarely returning errors even if the device is switched
|
|
off. Error detection is therefore likely to be minimal.
|
|
|
|
The file scanner.c provides a thin layer on top of scsi.c, and might
|
|
decode error returns if there were any.
|
|
|
|
The file scl.c implements many of the HP SCL (Scanner Control
|
|
Language) commands. This involves generating and parsing lots of
|
|
escape sequences.
|
|
|
|
The file gui.c provides a simple X interface to the scanner. It
|
|
allows you to preview the whole scan area, zoom in on the bit you're
|
|
interested in, and scan it to a file. So far it can only scan 24-bit
|
|
colour, preview on a colour display, and produce ppm files.
|
|
|
|
All of this has been hacked up in a hurry, so it's pretty minimal. It
|
|
has been tried only under FreeBSD 1.1 with a ScanJet IIcx connected to
|
|
an Adaptec 1542CF. I don't have much time to spend on it, so don't
|
|
expect rapid improvements. Please send bug-reports and improvements
|
|
to R.Tobin@ed.ac.uk.
