LC - Loop-Continue Mode
To repeat a test or series of tests endlessly, enter the prefix LC. This loop
includes everything on the command line.
To break the loop, press the BREAK key on the diagnostic video display
terminal. Certain tests disable the BREAK key interrupt, so it may become
necessary to press the abort or reset switches on the PowerPC board front
panel.
Example:
PPC x -Diag>lc;ram adr
RAM ADR: Addressability................. Running ---> PASSED
Pass Count =1, Errors This Pass =0, Total Errors =0
RAM ADR: Addressability................. Running ---> PASSED
Pass Count =2, Errors This Pass =0, Total Errors =0
RAM ADR: Addressability................. Running ---> PASSED
Pass Count =3, Errors This Pass =0, Total Errors =0
RAM ADR: Addressability................. Running ---> <BREAK>
--Break Detected--
PPC
x -Diag>
LE - Loop-On-Error Mode
Occasionally, when an oscilloscope or logic analyzer is in use, it becomes
desirable to repeat a test endlessly (loop) while an error is detected. The
LE command modifies the way a failed test is endlessly repeated.
The LE command has no effect until a test failure occurs, at which time, if
the LE command has been previously encountered in the user command
line, the failed test is re-executed as long as the previous execution returns
failure status.
To break the loop, press the BREAK key on the diagnostic video display
terminal. Certain tests disable the BREAK key interrupt, so it may become
necessary to press the abort or reset switches on the PowerPC board front
panel.
