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
       /etc/sane.d/dc25.conf
	      The  backend  configuration  file	 (see  also   description   of
	      SANE_CONFIG_DIR below).

       /usr/lib*/sane/libsane-dc25.a
	      The static library implementing this backend.

       /usr/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 /etc/sane.d.	If the
	      value of the environment variable ends with the directory	 sepa-
	      rator 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).

       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.
