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

          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.

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

          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 cam-
          era 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:

               This environment variable specifies the list of direc-
               tories 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 direc-
               tory separator character, then the default directories
               are searched after the explicitly specified directo-
               ries.  For example, setting SANE_CONFIG_DIR to
               "/tmp/config:" would result in directories tmp/config,
               ., and /etc/sane.d being 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 maxi-
               mally copious debug output; smaller levels reduce ver-


          Peter Fales,

          Known bugs/limitations are:

          I haven't figured out how to trigger an option reload fol-
          lowing 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 for
          details).  You must be subscribed to the list, otherwise
          your mail won't be sent to the subscribers.
