Hi, a year ago I found a Win2k SCSI driver for these scanners containing symbols. The driver was written by Acer, so these Agfa scanners are probably just rebranded.
According to the driver, there are two chipsets for these scanners. They are called 2103A and 7107P. My 1212P has the 2103A (it's written on a chip). I attached two files that might be helpful. umacer.c is a program that sends a INQUIRY SCSI command to the scanner and displays the reply as hexdump. snapscan-pp.diff is a diff against sane-backends 1.0.14 that adds parport support. It is based on snapscan-usb. Both open /dev/parport0 to lock the port and use inb/outb to do the IO. THE PATCH IS NOT READY FOR INCLUSION. They get out of sync on the scsi bus. Bytes get duplicated. A line is toggled for every byte, but I have no idea when the data lines are valid again. I only managed to scan a few lines. It is horribly slow, because it doesn't use EPP or ECP. Maybe implementing these will fix everything (EPP and ECP have hardware handshaking). I asked BenQ Germany for documentation, but they answered they couldn't find any for such an old scanner after having moved two times. They keep scanner documents for three years. BenQ USA didn't answer. Daniel -------------- next part -------------- A non-text attachment was scrubbed...
