Well, I do like the ide, but I don't like your patch :-)

There's already a generic keypad widget, which is used by some other
display (I don't remember which one at the moment), and should be easy
to integrate into the HD44780 driver. With this generic widget, you can
specify any expression which will be evaluated at key press.

So I want YOU to write a generic UDP send plugin :-)



bye, Michael
