sane-dc240(5) SANE Scanner Access Now Easy sane-dc240(5)

NAME

 sane-dc240 - SANE backend for Kodak DC240 Digital Camera

DESCRIPTION

 The sane-dc240 library implements a SANE (Scanner Access Now Easy)
 backend that provides access to the Kodak DC240 camera. THIS IS EX-
 TREMELY ALPHA CODE! USE AT YOUR OWN RISK!!

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 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
 printed.
 cmdrespause specifies how many usec (1,000,000ths of a second) to wait
 between writing the command and reading the result. 125000 seems to be
 the lowest I could go reliably.
 breakpause specifies how many usec (1,000,000ths of a second) between
 sending the "back to default" break and sending commands.
 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
 cmdrespause=125000
 breakpause=1000000

FILES

 /usr/local/etc/sane.d/dc240.conf
 The backend configuration file (see also description of
 SANE_CONFIG_DIR below).
 /usr/local/lib/sane/libsane-dc240.a
 The static library implementing this backend.
 /usr/local/lib/sane/libsane-dc240.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. On *NIX systems, the direc-
 tories are separated by a colon (`:'), under OS/2, they are sep-
 arated 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 /usr/lo-
 cal/etc/sane.d. If the value of the environment variable ends
 with the directory separator character, then the default direc-
 tories are searched after the explicitly specified directories.
 For example, setting SANE_CONFIG_DIR to "/tmp/config:" would re-
 sult in directories tmp/config, ., and /usr/local/etc/sane.d be-
 ing searched (in this order).
 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.

AUTHOR

 Peter S. Fales
 This backend borrows heavily from the sane-dc210(5) backend by Brian J.
 Murrell which is based somewhat on the sane-dc25(5) backend by Peter
 Fales.
 The manpage was largely copied from the sane-dc210(5) manpage.

BUGS

 The major limitation that I know of is that the backend assumes the di-
 rectory 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
 http://www.sane-project.org/mailing-lists.html for details). You must
 be subscribed to the list, otherwise your mail won't be sent to the
 subscribers.
