Table 1–2: Console I/O Mode Commands

Command Action

BOOT Initializes the processor and transfers execution to the VMB.

CONFIGURE Invokes an interactive mode that permits you to enter Q22-bus

device names, then generates a table of Q22-bus I/O page device

CSR addresses and interrupt vectors.

CONTINUE Causes the processor to begin instruction execution at the address

currently contained in the program counter (PC). Does not perform

a processor initialization.

DEPOSIT Deposits data into the address you specify. If you do not specify

an address space or data size qualiﬁer, the console uses the last

address space and data size used in a DEPOSIT, EXAMINE,

MOVE, or SEARCH command.

EXAMINE Examines the contents of the memory location or register of the

address you specify. If you do not specify an address, + is assumed.

FIND Searches main memory starting at address 0 (zero) for a page-

aligned 128-Kbyte segment of good memory, or a restart parameter

block (RPB).

HALT The HALT command has no effect. It is included for compatibility

with other VAX consoles.

HELP Displays the correct syntax for all console commands.

INITIALIZE Performs a processor initialization.

MOVE Copies the block of memory starting at the source address to a

block beginning at the destination address.

NEXT Executes the number of macro instructions you specify. If you do

not specify a number, 1 (one) is assumed.

REPEAT Repeatedly displays and executes the command you specify. Press

Ctrl/C

to stop the command. You can specify any valid console

command except the REPEAT command.

SEARCH Finds all occurrences of a pattern and reports the addresses where

the pattern was found. If you include the /NOT qualiﬁer, the

command reports all addresses for which the pattern did not

match.

SET BFLAG Sets the default R5 boot ﬂags. The value must be a hexadecimal

number of up to eight digits.

SET BOOT Sets the default boot device. The value must be a valid device

name.

SET CONTROLP Sets Control-P as the console halt condition, instead of a BREAK.

SET HOST Connects to the DUP or MAINTENANCE driver on the node or

device you specify.

SET LANGUAGE Sets the console language and keyboard type.

SET HALT Sets the halt action you deﬁne. Acceptable values are the following

keywords: default, restart, reboot, halt, restart_reboot, or a

number in the range 0 to 4 inclusive.
