       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 EXTREMELY ALPHA CODE!  USE AT YOUR OWN RISK!!


       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 printed.

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

       breakpause specifies how many usec (1,000,000ths of a second) between sending the "back to
       default" break and 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 static library implementing this backend.

              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.  On *NIX systems, 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 sane-dc210(5) backend by Brian J. Murrell which is
       based somewhat on the sane-dc25(5) backend by Peter Fales.

       The manpage was largely copied from the sane-dc210(5) 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.
