INTRODUCTION
I bought a Ricoh RDC-2E Digital camera which came with software that only ran under Microsoft Windows. Naturally there was no Linux support.
Welcome to version 0.8 of "rdc2e"; a program that runs on Linux which downloads pictures from the camera.
INSTALLATION
Read the INSTALL file for the (brief) installation instructions.
PREREQUESITS
You will also need to have the JPEG library installed along with "netpbm" utilities for the "j6itojpg" package to work.
The JPEG library is found on any good Linux/sunsite/metalabs mirror in the .../libs/graphics/ directory. On a RedHat distribution, use the 'libjpeg' RPM.
The "netpbm" is also available on a Linux/sunsite/metalabs mirror in the .../apps/graphics/convert/ directory. On a RedHat distribution, use the 'libgr-progs' RPM.
It is also HIGHLY recomended that you install 'irqtune' to improve the performance of your serial port. http://www.best.com/~cae/irqtune This sets the IRQ priority of the serial higher than that of the disk drives. If you don't, then expect to get CRC errors at times. These errors are just retries, but a little anoying.
HOW TO USE
This is a command line tool that is pretty basic in its use.
The easiest way to use it would be to use no options, and ALL images in the cameras memory (not the PCMCIA card) will be downloaded to the local directory using the internal names for each image. These are r0100001.j6i, r0100002.j6i, etc.
look at the man page ("man rdc2e") for an explanation of the command line arguements.
Then use the "j6iextract" command installed in /usr/local/bin to convert them to GIF, JPEG or TIFF files. Again, read the man page ("man j6iextract") for full details on its use. It's most basic use is "j6iextract *.j6i" which will create a JPEG (.jpg) file for each J6I file in the current directory.

It is here that I found out how to convert the J6I files to JPEG.
Take a look at:
ftp://ftp.itojun.org/pub/digi-cam/DC-2/dctools.0.04a.shar
for a good collection of utilities to convert the J6Is to JPEGs.
Clifford Wright - cliff@snipe444.org
Thanks to Cliffs work on the RDC-300 support in gPhoto I was able
to determine that the CRC used in the RDC-2E was that used in zmodem.

Leon found the value of a frame NAK. This makes retries possible
when a frame comes in with an invalid CRC (or length).
