Although Lua is not implemented using the COM (Component Object Model) interface, sometimes it is useful to be able to use COM from within your scripts.
[EDIT] (September 2010) The module luacom will let you access COM objects. This is now built into version 4.60 onwards of MUSHclient. Instead of following the instructions below about downloading luacom, simply do this:
This is possible if you download luacom from LuaForge, and use it in your Lua scripts.
