Help! I have been given a Datacopy model 230 scanner with a scsi interface
card and have been told to make it work with 1) a Microport AT machine and
2) an IBM RT. I'll worry about the Microport first, since I don't have
to deal with the RT's VRM.
This job is complicated by the fact that I don't have any technical docs
for the scanner (yet). I do have some pascal (ugh) code provided by the
Datacopy folks supposedly for a System V machine. Almost certainly,
all of the low level references have no relevance to the driver that
I want to build in C. Furthermore, the scsi interface card is
a DMA device, and I have no clue as to how to access it short
of hacking the kernel, quite a bit over my head (but hey, you
have to learn some time).
My questions are: a) has anyone attempted interfacing a scanner
to unix before? b) can anyone lead me in the right direction
in terms of DMA accessing schemes? c) Does the driver have to
be linked into the kernel? d) Can anyone suggest literature
on these subjects?
Please send me mail (path below), as my normal news connection is going
to end as of May 31, hopefully a temporary condition.
