User`s guide

The indirect command file CODEOl.CMD is one of four possible command files that can load
selected microcode into the
CPU WCS. The file used depends upon the presence of the FPA
and IDC. This presence is determined by a value passed to the console microprocessor from the
execution
of the microcode at OEOO (POWER. CPU). The values passed to the console
microprocessor to indicate which command file
is used are shown below.

o The console prompt is printed. The console subsystem is now ready to perform any console
command.
If the CONSOLE file is not found and the microdiagnostic file (ENSAA.EXE) is found on the tape
cartridge inserted into a tape drive unit, the
CPU enters the microdiagnostic monitor mode (see Chapter
4), and the console terminal prints the
MIC> prompt.

CONSOLE COMMAND LANGUAGE
When the
CPU is not executing instructions, it is in the console I/O mode idle loop. In this mode the CPU
is receptive to console commands. These commands enable the user to communicate with the V AX-
11/730 firmware from the console terminal. A console command is specified either as a control character
(CTRL/C) or as a single letter or word with optional modifiers.
This section
will cover commands that are VAX-II /730 processor-specific.

Table 2-5 lists the control characters and their functions for the console
I/O mode.
