NAME

       sane-dc240 - SANE backend for Kodak DC240 Digital Camera

DESCRIPTION

       The  sane-dc240  library  implements  a  SANE (Scanner Access Now Easy)
       backend that provides  access  to  the  Kodak  DC240  camera.  THIS  IS
       EXTREMELY ALPHA CODE!  USE AT YOUR OWN RISK!!

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 dc240.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 a 450MHz Pentium, I usually have no
       problems downloading at 115200 baud, though the camera sometimes has to
       resend  packets  due  to  lost characters.  Results are better when the
       "interrupt-unmask flag" is set in the IDE driver  (hdparm  -u1).   Sup-
       ported baud rates are: 9600, 19200, 38400, 57600, and 115200.

       The  dumpinquiry  line  causes  some information about the camera to be
       printed.

       cmdrespause specifies how many usec (1,000,000ths of a) between writing
       the  command  and reading the result should be used. 125000 seems to be
       the lowest I could go reliably.

       breakpause is the time in 1,000,000ths of a usec  between  sending  the
       "back to default" break sending commands.

       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
              cmdrespause=125000
              breakpause=1000000

FILES

       /usr/local/etc/sane.d/dc240.conf
              The  backend  configuration  file  (see  also   description   of
              SANE_CONFIG_DIR below).

       /usr/local/lib/sane/libsane-dc240.a
              The static library implementing this backend.

       /usr/local/lib/sane/libsane-dc240.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
              /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_DC240
              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.

AUTHOR

       Peter S. Fales

       This backend borrows heavily from the dc210 backend by Brian J. Murrell
       which is based somewhat on the dc25 backend by Peter Fales.

       The manpage was largely copied from the dc210 manpage.

BUGS

       The  major  limitation  that  I know of is that the backend assumes the
       directory in the camera is 100dc240.  Once the camera  has  taken  more
       than 9999 pictures, the directory will increment to 101dc240.  Not only
       should we check for the additional directory, but pictures may actually
       be found in multiple directories.

       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.
