       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 con‐
       nected.	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).	  Sup‐
       ported 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:

	      # 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 config‐
	      uration file is searched in two default directories: first,  the
	      current	 working   directory   (".")   and   then   in	 /sys‐
	      tem/resources/sane-backends/1.0.18/etc/sane.d.  If the value  of
	      the environment variable ends with the directory separator char‐
	      acter, 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	 "/system/resources/sane-back‐
	      ends/1.0.18/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.

       More general comments, suggestions, and inquiries  about	 frontends  or
       SANE   should   go   to	 the   SANE   Developers   mailing  list  (see for details).  You  must
       be  subscribed  to  the	list, otherwise your mail won't be sent to the
