  • Page 24: Console Mode Definition

    Overview Console Mode Definition In console mode, the system operates under the control of the console subsystem, rather than the operating system. All user input is passed to and interpreted by the console subsystem. Console mode is in effect when the system is turned on and the operating system software has not been started, or when the operating system has been shut down.

  • Page 25: Supported Keys And Control Characters

    Some console commands control system devices and memory. Do not use console commands without fully understanding the effect they can have on your DEC 3000 Model 300 Series AXP system. For instance, some advanced-level commands, such as deposit you manipulate nonvolatile and system memory.
