9<P>
10There are two programs written by myself
11(<A HREF="mailto:Oliver.Hartmann@t-online.de">Oliver.Hartmann@t-online.de</A>):
12<BR>
13DC20Term transfers the pictures out of the camera and stores they as raw
14data files - like the change for a new film. <BR>
15DC2toTGA converts those raw data files to standard image files - like the
16development of the film.
17<P>
18So you get the pictures out of your camera as quick as possible and you are
19ready for the next shots. Later, to get the best results, you can convert
20the raw data files to standard image files as often you like.
21<P>
22The actual versions of both programs are available for DOS, Win16, Win32
23and Linux. <BR>
24See:

29</H3>
30<P>
31For the first time, you can just plug in the camera and dump all the images
32out of it - only with one keystroke. No answering millions of questions with
33the mouse, and all the tedious work in the twain module and the image software,
34to finally end up the files in one directory.

99The program reads the data bytes sending by the camera via polling. Since
100the camera provides no handshake signals, this is a real time job and could
101go wrong in a multitasking environment. Maybe you must reduce the baud rate
102to avoid communication problems.
103<P>
104<H3>
105  Troubleshooting:
106</H3>
107<P>
108<UL>
109  <LI>
110    Best environment for the DOS version dc20term.exe is plain DOS
111  <LI>
112    Best interface is a hardware buffered com port (16550 UART with FIFO). Use
113    Option -F with the DOS version.
114  <LI>
115    If there is only a 8250 UART the maximum baud rate depends on your system
116    speed. Use option -B to find the optimum.
117  <LI>
118    If you want to use the DOS program in a multitasking environment (like
119    MS-Windows), run it in a high priority DOS-Box (e.g. through PIF). Full screen
120    mode works much better than a DOS window.
121  <LI>
122    Pay attention to correct parameter settings. If you start without any parameter
123    it works well in most cases (com port parameter is essential if not equal
124    to COM1). See 'Syntax Examples' below.
125</UL>
126<P>
127<H3>
128  Syntax Examples:<BR>
129</H3>
130<UL>
131  <LI>
132    DC20TERM -B57600 -C2 -F<BR>
133    means:<BR>
134    - baud rate: 57,600<BR>
135    - com port: 2 <BR>
136    - looking for a 16550 UART (com port with FIFO)
137  <LI>
138    Option -F:<BR>
139    without this option a FIFO is ignored,<BR>
140    with -F the program test the com port for a FIFO - if a FIFO will be found,
141    it will be used and there is a note 'xxx baud (using FIFO)' on the first
142    line - if no FIFO will be found you get the message 'xxx baud (no FIFO found)'
143    on the first line.
144  <LI>
145    default values are -B9600, -C1, ignore FIFO<BR>
146    In most cases it works well, but with 9600 baud the picture download takes
147    some minutes.
148  <LI>
149    I use the program with these parameters:<BR>
150    DC20TERM -B115200 -F<BR>
151    It works well (also under Win95) and the download of a high resolution picture
152    (124,928 byte) takes about 15 seconds.
153  <LI>
154    Option -V (version 1.43 or higher):<BR>
155    DC20TERM -V100<BR>
156    - takes 100 pictures in time-lapse video mode<BR>
157    - actions: erase, take picture, download, erase, take picture, ... and so
158    on<BR>
159    - frame rate depends on baud rate
160  <LI>
161    batch processing:<BR>
162    DC20TERM &lt;cmd.txt <BR>
163    or<BR>
164    DC20TERM -C2 -B115200 -F &lt;cmd.txt<BR>
165    - cmd.txt should contain the keystroke commands<BR>
166    - D command will not work in batch mode =&gt; use X command (version 1.43
167    or higher)

173<P>
174Versions before 1.40 convert only high resolution .dc2 files.<BR>
175<B>Version 1.40 or later now converts high and low res pictures.</B>
176<P>
177The images created with the Kodak software (or the Chinon software) and the
178output of DC2toTGA often differ. The main reason is the higher contrast of
179the Kodak images. You can get quite similar results with the parameter -v0.65.
180But you lose a lot of details in the shadows. That's why I set the gamma
181default to 0.5. Another difference is the color adjustment: Try changing
182of red factor (e.g. to 0.7 or 0.75) or blue factor (e.g. 0.9).
183<H3>
184  Syntax Examples:<BR>
185</H3>
186<UL>
187  <LI>
188    DC2toTGA -a<BR>
189    will convert all files stored with DC20term (e.g. DC_001.DC2 to DC_008.DC2)
190  <LI>
191    DC2toTGA my_pic1<BR>
192    will convert MY_PIC1.DC2
193  <LI>
194    DC2toTGA -x25<BR>
195    will convert the file DC_025.DC2
196  <LI>
197    DC2toTGA -x4 -a<BR>
198    will convert DC_004.DC2 and all files up to DC_999.DC2 (if exist)
199  <LI>
200    DC2toTGA -a -v0.7<BR>
201    will convert all files (see above) using a gamma value of 0.7 (more contrast)
202  <LI>
203    DC2toTGA -o0<BR>
204    no finishing (sharpen)
205</UL>
206<P>
207In&nbsp;most cases the default values are good enough. If the resulting image
208looks bad, start again with different settings for saturation, gamma value
209or norm_percentage.
