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

   /usr/lib/arch_triplet/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.
