Note that this only works if you have a working shell on _another_ terminal, so if you're e.g. working with an emulation which has only one working terminal, and your raw-mode program on it has gone berserk, 'See Figure 1'. It really is advised to have another working terminal if you want to play with raw-mode programs. Noel
