Research direction
The issue is about the IRCListener returning 'Unknown command' for the MODE command, which is a standard IRC command. The fix involves adding a handler for MODE in the IRCListener class, similar to other commands like JOIN or NICK. Examine the existing command pattern (e.g., in files like irc listener.py) and implement a handler that either processes the MODE command or silently ignores it if not needed. The issue reporter indicates the client irssi sends MODE asdf, so the handler should parse and respond appropriately (e.g., with an empty reply or a proper MODE response). No linked PRs or maintainer comments exist, so the solution is straightforward.
