OK. This should not happen to any of us, but the fact remains that from time to time we try to view a binary file before we make sure it is viewable. We simply forget to check and assume that it will be a viewable text file. In any case, the result is that we end up with a lot of scrambled characters on the screen and we don\’t know how to get out of the situation. Well, in most cases simply typing reset will do it, even if you cannot see what you are typing.
