sane-dc240 - SANE backend for Kodak DC240 Digital Camera


   The  sane-dc240  library  implements  a  SANE (Scanner Access Now Easy)
   backend that provides  access  to  the  Kodak  DC240  camera.  THIS  IS


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


   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).
   Supported baud rates are: 9600, 19200, 38400, 57600, and 115200.

   The  dumpinquiry  line  causes  some information about the camera to be

   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:

          The  backend  configuration  file  (see  also   description   of
          SANE_CONFIG_DIR below).

          The shared library implementing this backend (present on systems
          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
          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).

          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.

   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.


   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.
