NAME

6       sane-dc240 - SANE backend for Kodak DC240 Digital Camera
7

DESCRIPTION

9       The  sane-dc240  library  implements  a  SANE (Scanner Access Now Easy)
10       backend that provides  access  to  the  Kodak  DC240  camera.  THIS  IS
11       EXTREMELY ALPHA CODE!  USE AT YOUR OWN RISK!!
12

DEVICE NAMES

14       The  current  version  of the backend only allows one camera to be con‐
15       nected.  The device name is always "0".
16

CONFIGURATION

18       The contents of the dc240.conf specify the serial port and baud rate to
19       use.  The baud rate specifies the maximum rate to use while downloading
20       pictures.  (The camera is always  initialized  using  9600  baud,  then
21       switches  to  the higher rate).  On a 450MHz Pentium, I usually have no
22       problems downloading at 115200 baud, though the camera sometimes has to
23       resend  packets  due  to  lost characters.  Results are better when the
24       "interrupt-unmask flag" is set in the IDE driver  (hdparm  -u1).   Sup‐
25       ported baud rates are: 9600, 19200, 38400, 57600, and 115200.
26
27       The  dumpinquiry  line  causes  some information about the camera to be
28       printed.
29
30       cmdrespause specifies how many usec (1,000,000ths of a) between writing
31       the  command  and reading the result should be used. 125000 seems to be
32       the lowest I could go reliably.
33
34       breakpause is the time in 1,000,000ths of a usec  between  sending  the
35       "back to default" break sending commands.
36
37       Empty  lines  and  lines  starting with a hash mark (#) are ignored.  A
38       sample configuration file is shown below:
39
40              port=/dev/ttyS0
41              # this is a comment
42              baud=115200
43              dumpinquiry
44              cmdrespause=125000
45              breakpause=1000000

FILES

48       /etc/sane.d/dc240.conf
49              The  backend  configuration  file  (see  also   description   of
50              SANE_CONFIG_DIR below).
51
52       /usr/lib64/sane/libsane-dc240.a
53              The static library implementing this backend.
54
55       /usr/lib64/sane/libsane-dc240.so
56              The shared library implementing this backend (present on systems
57              that support dynamic loading).

ENVIRONMENT

61       SANE_CONFIG_DIR
62              This environment variable specifies the list of directories that
63              may contain the configuration file.  Under UNIX, the directories
64              are separated by a colon (`:'), under OS/2, they  are  separated
65              by a semi-colon (`;').  If this variable is not set, the config‐
66              uration file is searched in two default directories: first,  the
67              current working directory (".") and then in /etc/sane.d.  If the
68              value of the environment variable ends with the directory  sepa‐
69              rator character, then the default directories are searched after
70              the explicitly  specified  directories.   For  example,  setting
71              SANE_CONFIG_DIR  to  "/tmp/config:"  would result in directories
72              tmp/config, ., and /etc/sane.d being searched (in this order).
73
74       SANE_DEBUG_DC240
75              If the library was compiled with debugging support enabled, this
76              environment  variable controls the debug level for this backend.
77              A value of 128 requests maximally copious debug output;  smaller
78              levels reduce verbosity.

89       This backend borrows heavily from the dc210 backend by Brian J. Murrell
90       which is based somewhat on the dc25 backend by Peter Fales.
91
92       The manpage was largely copied from the dc210 manpage.

BUGS

96       The major limitation that I know of is that  the  backend  assumes  the
97       directory  in  the  camera is 100dc240.  Once the camera has taken more
98       than 9999 pictures, the directory will increment to 101dc240.  Not only
99       should we check for the additional directory, but pictures may actually
100       be found in multiple directories.

102       More general comments, suggestions, and inquiries  about  frontends  or
103       SANE   should   go   to   the   SANE   Developers   mailing  list  (see
104       http://www.sane-project.org/mailing-lists.html for details).  You  must
105       be  subscribed  to  the  list, otherwise your mail won't be sent to the
106       subscribers.
