Loop break stop is designed to terminate the process currently running if the
process is interrupted for a preset period of time. The loop break stop senses
that nothing is happening in the process and turns the process off.
Enter an elapsed time using the UP and DOWN arrow keys. For slow sys-
tems, a longer time should be entered.
