Invoking a loop on diagnostics in a workstation of a computer system with only a power connection and without having any switches or keyboard for input is facilitated through a diagnostic control program resident on each workstation. The diagnostic control program takes a basic sequence flow, as set forth in the drawing. The major block is the set of POR (Power On Reset) diagnostics that execute each time the workstation is turned on. Once the tests complete, two major checks are made by the control program. The first is to see if the keyboard is attached. If it is attached, the terminal can go into its normal operation or handle other errors accordingly. If the keyboard is not attached, then the first condition for the 'Auto Loop' mode is satisfied.
