    CHAPTER 5: Operation If the timeout is set for zero, this is an instant timeout. Two keyboards each set for a zero timeout and connected to the same CPU will appear to both be connected to the CPU. If the timeout is set for 255, this is an infinite timeout. A CPU will not be released, until another port is switched to or the timeout is changed, from the keyboard with the infinite timeout.
