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

       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

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

       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  ini-
       tialized  using 9600 baud, then switches to the higher rate).  On my 90MHz Pentium, I usu-
       ally 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 dur-
       ing  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  net-

       Empty  lines  and lines starting with a hash mark (#) are ignored.  A sample configuration
       file is shown below:

	      # this is a comment

	      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.  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 vari-
	      able controls the debug level for this backend.  A value of 128 requests	maximally
	      copious debug output; smaller levels reduce verbosity.

       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.mostang.com/sane/mail.html for details).  You
       must be subscribed to the list, otherwise your mail won't be sent to the subscribers.
