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


       The sane-dc25 library implements a SANE (Scanner Access Now Easy) back‐
       end 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  con‐
       nected.  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 exces‐
       sively busy and the "interrupt-unmask flag" is set in  the  IDE  driver
       (hdparm -u1).  Supported baud rates are: 9600, 19200, 38400, 57600, and

       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:

              SANE_CONFIG_DIR below).

              that support dynamic loading).


              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 config‐
              uration 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  sepa‐
              rator 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

              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.




       Peter Fales,


       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 exam‐
       ple, the slider that is used to select the picture from the camera  may
       not be updated immediately.
