.SH NAME
|
|
sane\-dc240 \- SANE backend for Kodak DC240 Digital Camera
|
|
.SH DESCRIPTION
|
|
The
|
|
.B 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!!
|
|
.SH "DEVICE NAMES"
|
|
The current version of the backend only allows one camera to be
|
|
connected. The device name is always "0".
|
|
.SH CONFIGURATION
|
|
The contents of the
|
|
.I 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.
|
|
.PP
|
|
The dumpinquiry line causes some information about the camera to
|
|
be printed.
|
|
.PP
|
|
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.
|
|
.PP
|
|
breakpause is the time in 1,000,000ths of a usec between sending the
|
|
"back to default" break sending commands.
|
|
.PP
|
|
Empty lines and lines starting with a hash mark (#) are
|
|
ignored. A sample configuration file is shown below:
|
|

.SH FILES
|
|
.TP
|
|
.I @CONFIGDIR@/dc240.conf
|
|
The backend configuration file (see also description of
|
|
.B SANE_CONFIG_DIR
|
|
below).
|
|
.TP
|
|
.I @LIBDIR@/libsane\-dc240.a
|
|
The static library implementing this backend.
|
|
.TP
|
|
.I @LIBDIR@/libsane\-dc240.so
|
|
The shared library implementing this backend (present on systems that
|
|
support dynamic loading).
|
|
|
|
.SH ENVIRONMENT
|
|
.TP
|
|
.B 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 configuration file
|
|
is searched in two default directories: first, the current working
|
|
directory (".") and then in @CONFIGDIR@. 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
|
|
.B SANE_CONFIG_DIR
|
|
to "/tmp/config:" would result in directories "tmp/config", ".", and
|
|
"@CONFIGDIR@" being searched (in this order).
|
|
.TP
|
|
.B SANE_DEBUG_DC240
|
|
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.
|
|
.PP
|
|
The manpage was largely copied from the dc210 manpage.
|
|
|
|
.SH BUGS
|
|
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.
