Log on to the Windows PC in the Digital Design & Microprocessor Lab. You should have access to your usual home directory. Start up the terminal emulation program as instructed by the demonstrator. Turn on the SBC, and the dBug command line should appear in the terminal screen:

The black button on the SBC is for a software ABORT, while the red button initiates a complete HARD RESET. In most cases it should suffice to use the ABORT button to stop a user program.
