The sane-dc240 library implements a SANE (Scanner Access Now Easy)
backend that provides access to the Kodak DC240 camera. THIS IS
EXTREMELY ALPHA CODE! USE AT YOUR OWN RISK!!
The current version of the backend only allows one camera to be con-
nected. The device name is always "0".
The contents of the dc240.conf specify the serial port and baud rate to
use. The baud rate specifies the maximum rate to use while downloading
pictures. (The camera is always initialized using 9600 baud, then
switches to the higher rate). On a 450MHz Pentium, I usually have no
problems downloading at 115200 baud, though the camera sometimes has to
resend packets due to lost characters. Results are better when the
"interrupt-unmask flag" is set in the IDE driver (hdparm -u1). Sup-
ported baud rates are: 9600, 19200, 38400, 57600, and 115200.
The dumpinquiry line causes some information about the camera to be
cmdrespause specifies how many usec (1,000,000ths of a) between writing
the command and reading the result should be used. 125000 seems to be
the lowest I could go reliably.
breakpause is the time in 1,000,000ths of a usec between sending the
"back to default" break sending commands.
Empty lines and lines starting with a hash mark (#) are ignored. A

This backend borrows heavily from the dc210 backend by Brian J. Murrell
which is based somewhat on the dc25 backend by Peter Fales.
The manpage was largely copied from the dc210 manpage.
The major limitation that I know of is that the backend assumes the
directory in the camera is 100dc240. Once the camera has taken more
than 9999 pictures, the directory will increment to 101dc240. Not only
should we check for the additional directory, but pictures may actually
be found in multiple directories.
