There isn't any timeout involved, or "no answer". The delay is about three to four seconds long, but maybe it depends on the speed of the (emulated) RSTS host too. I do know that there is not such a thing as a "no answer"; it was just an oversimplification of what a casual user could think upon seeing an error instead of a login prompt. :) G.
