sane-dc240 - SANE backend for Kodak DC240 Digital Camera
The sane-dc240 library implements a SANE (Scanner Access Now Easy)
backend that provides access to the Kodak DC240 camera. THIS IS EX-
TREMELY 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 second) to wait
between writing the command and reading the result. 125000 seems to be
the lowest I could go reliably.
breakpause specifies how many usec (1,000,000ths of a second) between
sending the "back to default" break and sending commands.
Empty lines and lines starting with a hash mark (#) are ignored. A
sample configuration file is shown below:

The static library implementing this backend.
The shared library implementing this backend (present on systems
that support dynamic loading).
This environment variable specifies the list of directories that
may contain the configuration file. On *NIX systems, the direc-
tories are separated by a colon (`:'), under OS/2, they are sep-
arated by a semi-colon (`;'). If this variable is not set, the
configuration file is searched in two default directories:
first, the current working directory (".") and then in /usr/lo-
cal/etc/sane.d. If the value of the environment variable ends
with the directory separator character, then the default direc-
tories are searched after the explicitly specified directories.
For example, setting SANE_CONFIG_DIR to "/tmp/config:" would re-
sult in directories tmp/config, ., and /usr/local/etc/sane.d be-
ing searched (in this order).
If the library was compiled with debugging support enabled, this
environment variable controls the debug level for this backend.
A value of 128 requests maximally copious debug output; smaller
levels reduce verbosity.

This backend borrows heavily from the sane-dc210(5) backend by Brian J.
Murrell which is based somewhat on the sane-dc25(5) backend by Peter
The manpage was largely copied from the sane-dc210(5) manpage.
The major limitation that I know of is that the backend assumes the di-
rectory 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.
