Description 

Stop 

Bypass POST. This command does not depend on security mode. (Note: Some systems bypass POST as a default. In such cases, use Stop-D to start POST). 

Stop-A 

Abort. 

Stop-D 

Enter the diagnostic mode (set diag-switch? to true).

Stop-F 

Enter Forth on TTYA instead of probing. Use fexit to continue with the initialization sequence. Useful if hardware is broken.
