There was someone recently that posted that they had some sort of remote debuging working over an ethernet (or at least that they ALMOST had it working.). I remember thinking "Cool". I have however had good success with the serial crossover cables needed for the curren serial debugger. I know of course that it's not as convenient but the serial debugger can possibly work in network debugging situations where the ethernet debugger is "too close to the action" :-) I'll see if I can find the reference in the archives... julian On Tue, 19 Feb 2002, George V.
