Yes, with gphoto2 (which runs on Linux, and Mac OS X via the Terminal using MacPorts; not aware of any Windows equivalents, unless you run Linux as a VM).
Heard about gphoto2 but unfortunately i'm using windows. Is there any counterpart of gphoto2. Its been 2 years since the release of 7d. I thought someone will produce it already. Well maybe not my luck to hope such thing for now, yet again
