NAME
       sane-dc25 - SANE backend for Kodak DC20/DC25 Digital Cameras

DESCRIPTION
       The sane-dc25 library implements a SANE (Scanner Access Now Easy)
       backend that provides access to Kodak DC20 and DC25 cameras.  At
       present, only the DC25 has been tested, but since the code is based on
       a DC20 interface program, it is likely to work for that model also.

DEVICE NAMES
       The current version of the backend only allows one camera to be
       connected.  The device name is always "0".

CONFIGURATION
       The contents of the dc25.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 my 90MHz Pentium, I usually have no
       problems downloading at 115200 baud as long as the system is not
       excessively busy and the "interrupt-unmask flag" is set in the IDE
       driver (hdparm -u1).  Supported baud rates are: 9600, 19200, 38400,
       57600, and 115200.

       The dumpinquiry line causes some information about the camera to be
       printed to stderr during startup.  Note:  This is not compatible with
       saned, so make sure you don't have any dumpinquiry lines if you are
       using saned (i.e. scanning on a remote machine using a network).

       Empty lines and lines starting with a hash mark (#) are ignored.  A
       sample configuration file is shown below:

              port=/dev/ttyS0
              # this is a comment
              baud=115200
              dumpinquiry

FILES
       /etc/sane.d/dc25.conf
              The backend configuration file (see also description of
              SANE_CONFIG_DIR below).

       /usr/local/lib/sane/libsane-dc25.a
              The static library implementing this backend.

       /usr/local/lib/sane/libsane-dc25.so
              The shared library implementing this backend (present on systems
              that support dynamic loading).


ENVIRONMENT
       SANE_CONFIG_DIR
              This environment variable specifies the list of directories that
              may contain the configuration file.  Under UNIX, the directories
              are separated by a colon (`:'), under OS/2, they are separated
              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
              /etc/sane.d.  If the value of the environment variable ends with
              the directory separator character, then the default directories
              are searched after the explicitly specified directories.  For
              example, setting SANE_CONFIG_DIR to "/tmp/config:" would result
              in directories "tmp/config", ".", and "/etc/sane.d" being
              searched (in this order).

       SANE_DEBUG_DC25
              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.

BUGS
       Known bugs/limitations are:

       I haven't figured out how to trigger an option reload following a
       "scan."  This causes problems when a new picture is snapped for
       example, the slider that is used to select the picture from the camera
       may not be updated immediately.

       More general comments, suggestions, and inquiries about frontends or
       SANE should go to the SANE Developers mailing list (see
       http://www.sane-project.org/mailing-lists.html for details).  You must
       be subscribed to the list, otherwise your mail won't be sent to the
       subscribers.
