(Wavy time-travel effect) DG's Dasher terminals had a set cursor position (^P <byte> <byte>) and read-out cursor position (^E) which could be combined using an AOS CLI SEND command and the [!ASCII] pseudo-macro to crash another user's terminal session: SEND @con27 Die! Die! Die! [!ASCII 20 3 2 5] (octal 20 3 2 5 == ^P ^C ^B ^E, where ^C ^B was the code to kill the process associated with the terminal) If you got a terminal into binary mode you could make the line go catatonic with ^P ^E ^E ^E ... And, yes, DG eventually had to filter out certain control characters to spoil the fun. -- cP
