Something like
dd if=/dev/acd0c of=ISO bs=2k
should do it, but I've noticed that it sometimes gets an extra block at
the end which wasn't part of the original ISO file. If you know the
original size, you're in luck (either chop extra off, or use dd's
count argument), otherwise I suspect the extra block will be harmless
for most purposes.
