Certainly. A command (multiple bytes, usually) is sent to the camera, then, to determine whether or not the command was successful, the device that sent the command waits for a response, either "ACK" or "NCK" -- meaning ACKnowledged or Not aCKnowledged.

As for the original poster's problem, I have seen some odd behavior during initialization that would suggest that the camera doesn't receive what I send it--the reinitialization restarts 5-10 times when I boot the robot. I don't have a solution for this; maybe someone else here does.
