According to the docs, I can have my TCC Plugin handle an UNKNOWN_CMD, but I've failed to get this working. In one place in the docs, its says my plugin should implement UNKNOWN_CMD as a "function" and in another place it says my plugin should implement UNKNOWN_CMD as a "command." But neither of these work, my plugin is never called in either case. Other functions and commands in my plugin work just fine so I don't think I'm doing anything obviously wrong. I was just wondering if anyone has successfully implemented UNKNOWN_CMD in a plugin and what the trick is to get it working.
