That's because the keypresses that gtk+ deals with are simply X  
events, not characters on a serial terminal stream.

I took that approach in gish, where i faked out the Tk portion of  
Readline.

But it is important that you set up STDIN properly to give you all  
the characters pressed, instead of using line-buffering.  Readline  
does that for you...  in your own app, you'll have to use the termios  
stuff from the POSIX module.
