I don't know why this works since interrupts are obviously disabled. That's what I meant didn't work (ddb doesn't have scrollback itself). You're right that it sort of works if you hit a key [that causes output]. I think this is because the scrollback happens to be handled in the output routine although it is not handled in the normal way by the timeout routine. Switching of consoles has similar problems. Output fixes some of the problems by updating the screen, but output is only done when vt0 is the current vt so doing extra output doesn't help much, it just completes switches back to vt0. Bruce
