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

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.
