I would also be interested in what people have to say about
setting ioctl for devices like printers.  I have been trying
to write a graphics dump routine for my MSDOS computer (not IBM
compatible), and was having trouble.  I was opening the printer
as a binary device, but MSDOS was *not* treating like a binary
device/file.  If I wrote the info to a file first, then did
COPY <fname> PRN: /B, it printed the info fine.

I am mainly interested in setting devices to raw/cooked mode from
C.  Any help would be appreciated.
