Using PPCBug

PPCBug is command-driven; it performs its various operations in response to commands that you enter at the keyboard. When the PPC1-Bugprompt appears on the screen, the debugger is ready to accept debugger commands. When the PPC1-Diagprompt appears on the screen, the debugger is ready to accept diagnostic commands. To switch from one mode to the other, enter SD.
