Audit Companion Quiet Mode Reference When AC is "quiet" it blanks the screen and stops checking for keypresses. It will wake up for a <Control+Break> keypress or an alarm. Quiet mode can be used in a macro to exit AC at a specified time. This feature allows AC to be used in a batch file to run another program at a specified time. Quiet mode is also useful if you wish to leave AC running in a multi-tasking environment.
