I'd like to use it under FreeBSD. : For what it's worth, we tried to get the HP manual that describes this : scanner's SCSI command set -- for the purpose of writing our own : device driver -- and they would not sell it to us. : But if someone else has gotten around this, I'd like to know about it. Huh? There is nothing unique about the commands it uses. READ/WRITE of char streams that contain the escape sequences documented in the SCL manual is all you need. The scanner reports itself as a PROCESSOR device as I recall and you just need to issue READ/WRITE scsi calls to it. The SCL manual is freely available from HP and the DOS libraries that came with it ported without problems. Of course you will have to write the applications to actually do something with the scanner. I started with the PBMPlus package and wrote a scanjet too PPM convert in about an hour or so. This isn't at tough as everyone thinks. HP has done most of the work with the SCL libraries and making sure the scanjet used standard scsi cmds. -- Brian W.
