Scan for OS/2 1.3 by Kent Cedola
Copyright Kent Cedola 1991. All rights reserved.
The software and accompanying written materials are provided "AS IS"
without warranty of any kind. The entire risk as to the results and
performance of the software is assumed by you. In no event shall Kent

or inability to use this software.
The file 'SCAN.EXE' is a prototype (pre-alpha) of a scanning application
that I was working on under OS/2 1.X. To continue I needed to allocate
some rather large arrays to hold 256 gray-scale images and decided to move
to the 32bit platform of OS/2 2.0. Since I don't know of any ScanJet
support for OS/2, I decided to make this prototype available at this time.
Please realize that this application has NOT BEEN FULLY TESTED, but it is
better than nothing. So this would be a good time to think about a
backup of your data.
The current version of Scan can read and write .PCX files, clip data to
the clipboard and scan images from the HP ScanJet and ScanJet Plus
scanners. If you try reading/writing a non-PCX file you will get a 'soft'
abort of the scan application (but OS/2 will continue to run, unlike Windows).
I'm not going to tell you how to run Scan as I want to find out just how
'user friendly' this application is. If you have a problem then I will
redesign that area to make it easier for future users. (It's a pretty
simple program).
To continue you need to install one of two device drivers that do work
under OS/2 1.2, 1.3 and 2.0 on my hardware, which doesn't mean it will
work on your hardware. SCANJET1.SYS is for ISA (AT type) adapters and
SCANJET2.SYS is for MCA adapters. Just add "DEVICE=SCANJET?.SYS" (replace
the '?' with '1' or '2' depending on your hardware) to your CONFIG.SYS
file and re-boot your computer normally. If the driver doesn't initialize
you may need to consult your HP manual and change the switches on the HP
ScanJet adapter. The driver will read the settings off the board on it's
own and display them on the screen during booting.
After the driver is installed, turn on your scanner and run SCAN. If you
have any comments, suggestions or problems you can contact me on
CIS 72230,1451 or write to me at 2015 Meadow Lake Court, Norfolk Va 23518-5307.
I'm currently working on a much better version of Scan for OS/2 2.0 that
will fix a number of problems and expand the features a bit. If you like
to be an alpha and/or beta tester for the OS/2 2.0 (32bits) version then
please contact me at the above locations. Remember that what you see is only
a prototype and future versions will be much better.
What about other scanners? Send me your request and I'll see what I can do.
For those that want to use the scanner driver directly (programmer types).
Just open the file "SCAN01$" (same name for both drivers) and just do simple
DosRead() and DosWrite() to it. I highly recommend using 16k input buffers
for the DosRead(). Of course this assumes you have the manual on the HP
scanner control codes.
