These days I have tested l4con on my machine. First I just move the l4con package into my L4Linux directory and modify my menu.lst, but I can't get the result. Then I copy the menu.lst from the wiki, and it's ok. Now I have several questions and hope someone helps me.
This is my own menu.lst

The next one is what I got from the web.

Compare the two, first I find my own has a events module more and some options about events, then I add these to the one I got from the web, but it runs ok without any problem.
Then I changed the last lines' sequence and my own menu.lst works. Maybe that's the problem, but I'm not very sure.

Another thing puzzled me was that when I entered in the l4con and in the command line state, I wanted to quit from the l4con and input Q, then the messge is "input 'y' to quit",  I  input 'y', but it's not responding, when I input 'z', it says OK, what does this mean??
