## NAME

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

## DESCRIPTION

           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.

## DEVICE NAMES

           The current version of the backend only allows one camera  to  be  con-
           nected.  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 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
           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

           /usr/local/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 config-
                  uration file is searched in two default directories: first,  the
                  current     working     directory     (".")    and    then    in
                  /usr/local/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 directo-
                  ries.   For  example,  setting SANE_CONFIG_DIR to "/tmp/config:"
                  would   result   in   directories   "tmp/config",    ".",    and
                  "/usr/local/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 exam-
           ple, the slider that is used to select the picture from the camera  may
           not be updated immediately.
