Console Commands
This chapter describes the console commands that you can enter when the system
is in console mode. The system displays the console prompt (»» when it is
in console mode. If the system is running the operating system software, see
Chapter 2 for information on returning the system to console mode.
If the console security feature is enabled and a security password is set, you
must log in to privileged console mode before using most of these commands. See
Chapter 2 for information on the console security feature.
The following sections describe all the console commands, give the command
format, and describe the significance of each parameter. The VAX Software
Handbook contains a detailed description of each command and its parameters
and qualifiers.

3.1 BOOT
The BOOT command initializes the processor and executes the VMB (virtual
memory block) program. The VMB program tries to boot the operating system
from the specified device or list of devices, or from the default boot device if none
is specified. The console qualifies the bootstrap operation by passing a boot flags
bitmap to the VMB program in RS.
Format:

BOOT [qualifier-list] [{boot_device},fboot_device},...]
If you do not enter either the qualifier or the device name, the default value is
used. Explicitly stating the boot flags or the boot device overrides, but does not
permanently change, the corresponding default value.
When specifying a list of boot devices (up to 32 characters, with devices separated
by commas and no spaces), the system checks the devices in the order specified
and boots from the first one that contains bootable software.

Console Commands 3-1

Note

If you include the Ethernet device, EZAO, in a string of boot devices,
it must be placed only as the last device of the string. The system
continuously tries to boot from EZAO.
Set the default boot device and boot flags using the SET BOOT and SET BFLAG
commands. If you do not set a default boot device, the processor times out after
30 seconds and continuously tries to boot from the Ethernet device, EZAO. To
disable the autoboot feature, use three periods in place of the device name for the
SET BOOT command (SET BOOT . . . ).
Qualifiers:

Command specific:

/{boot_flags}

[device_name]

A 32-bit hexadecimal value passed to the VMB program in RS. The
console does not interpret this value. Use the SET BFLAG command
to specify a default boot flags longword. Use the SHOW BFLAG
command to display the longword.
Same as 1R5:{boot_flags}
A character string of up to 17 characters. Longer strings cause a
VAL TOO BIG error message. When specifying a list of boot devices,
separate the device names using commas. Do not use spaces. The
console checks the length of the device name, but does not interpret
or validate it. The console converts the string to uppercase, then
passes the VMB program a string containing the device name in RO.
Use the SET BOOT command to specify a default boot device or list
of devices. Use the SHOW BOOT command to display the default
bOot device. The factory default device is the Ethernet device, EZAO.
Table 2-1 lists the boot devices supported by the Model 85/95 system.

3-2 Console Commands

3.2 CONTINUE
The CONTINUE command causes the processor to begin instruction execution
at the address currently contained in the program counter (PC). This address is
the address stored in the PC when the system enters console mode or the address
that the user specifies using the DEPOSIT command. The CONTINUE command
does not perform a processor initialization.
Format:
CONTINUE

Example:
»>CONTlNUE
!OpenVMS DeL prompt

3.3 DEPOSIT
The DEPOSIT command deposits data into the address specified. 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. After processor initialization, the default address space is physical
memory, the default data size is longword, and the default address is zero. If you
specify conflicting address space or data sizes, the console ignores the command
and issues an error message.
Format:

DEPOSIT [qualifier-list] {address} {data} [data•••]
Qualifiers:
Data control: fB,!W, IL, IQ, 1N:{count}, ISTEP:{size}, !WRONG
Address space control: IG, II, 1M, /P, IV, /U
Arguments:
{address}
{data}

A longword address that specifies the first location into which data is
deposited. The address can be an actual address or a symbolic address.
The data to be deposited. If the specified data is larger than the deposit data
size, the firmware ignores the command and issues an error response. If the
specified data is smaller than the deposit data size, the data is extended on
the left with zeros.

[{data}]

Additional data to be deposited (as many as can fit on the command line).

Console Commands 3-3

Examples:
»>D/P/B/N:1FF 0 0

Clear first 512 bytes of
physical memory.

»>D/V/L/N:3 1234 5

Deposit 5 into four longwords
starting at virtual memory address
1234.

»>D/N:8 RO EEEEEETF

Loads GPRs RO through R8 with -1.

»>D/L/P/N:10/ST:200 0 8

Deposit 8 in the first longword of
the first 17 pages in physical
memory.

»>D/N:200 - 0

Starting at previous address, clear
513 longwords or 2052 bytes.

3.4 EXAMINE
The EXAMINE command examines the contents of the memory location or
register specified by the address. If no address is specified, + is assumed. The
display line consists of a single character address specifier, the physical address
to be examined, and the examined data.
EXAMINE uses the same qualifiers as DEPOSIT. However, the /WRONG
qualifier causes EXAMINE to ignore ECC errors when reading from physical
memory. The EXAMINE command also supports an /INSTRUCTION qualifier
that disassembles the instructions at the current address.

Format:
EXAMINE [qualifier-list] [address]

Qualifiers:
Data control: /B, /W, IL, /Q, 1N:{count}, /STEP:{size}, /WRONG
Address space control: /G, /I, fM, IP, N, /U
Command specific:
/INSTRUCTION

Disassembles and displays the VAX.. MACR0-32 instruction at the
specified address.

Arguments:
[{address}]

A longword address that specifies the first location to be examined.
The address can be an actual or a symbolic address. If no address is
specified, + is assumed.

3.5 FIND
The FIND command searches main memory, starting at address zero for a
page-aligned 128K-byte segment of good memory, or a restart parameter block
(RPB). If the command finds the segment or RPB, its address plus 512 is left.
in SP (R14). If it does not find the segment or RPB, the console issues an error
message and preserves the contents of SP. If you do not specify a qualifier, IRPB
is assumed.
Format:

3.9 LOGIN
Allows you to put the system in privileged console mode. When the console
security feature is enabled (see Section 2.2) and when you put the system in
console mode, the system operates in unprivileged console mode. You can access
only a subset of the console commands. To access the full range of console
commands, you must enter this command. The format of this command is as
follows:
LO[GIN]

When you enter the command, the system prompts you for a password as follows:
Password:

You must enter the current console security password. If you do not enter the
correct password, the system displays the error message, ILL PSWD. When
you enter the console security password, the system operates in privileged
console mode. In this mode, you can use all the console commands. The system
exits from privileged console mode when you enter one of the following console
commands:
•

BOOT

•

CONTINUE

•

HALT

•

START

3.10 MOVE
The MOVE command copies the block of memory starting at the source address
to a block beginning at the destination address. Typically, this command has
an IN qualifier so that blocks of data are transferred. The destination correctly
reflects the contents of the source, regardless of the overlap between the source
and the data.

Console Commands 3-9

The MOVE command performs byte, word, longword, and quadword reads and
writes to moving the data efficiently. The MOVE command supports physical and
virtual address spaces only.

Format:

MOVE [qualifier-list] Isrc_address} Idest_address}
Qualifiers:
Data control: IB, /W, IL, /Q, 1N:{count}, /STEP:{size}, !WRONG
Address space control: "N, /U, /P
Arguments:
{src_address}

A longword address that specifies the first location of the source data to
be copied.

{dest_address}

A longword address that specifies the destination of the first byte of data.
These addresses may be an actual address or a symbolic address. If no
address is specified, + is assumed.

Examples:
»>EX/N:4 0

3-10 Console Commands

3.11 NEXT
The NEXT command executes the specified number of macro instructions. If no
count is specified, 1 is assumed. After the last macro instruction is executed, the
console reenters console VO mode.

Format:
NEXT {count)

The console implements the NEXT command using the trace trap enable and
trace pending bits in the PSL and the trace pending vector in the SCB.
The console enters the Spacebar Step Mode. In this mode, pressing the spacebar
initiates each single step, and a carriage return forces a return to the console
prompt. The following restrictions apply:
•

If memory management is enabled, the NEXT command works only if the
first page in SSC RAM is mapped in SO (system) space.

•

Overhead associated with the NEXT command affects the execution time of
an instruction.

•

The NEXT command elevates the IPL to 31 for long periods of time
(milliseconds) while single-stepping over several commands.

•

Unpredictable results occur if the macro instruction being stepped over
modifies either the SCBB or the trace trap entry. This means that you cannot
use the NEXT command with other debuggers. You must validate PR$_SCCB
before using the NEXT command.

Arguments:
{count}

A value representing the number of macro instructions to execute.

Examples:

3.13 SEARCH
The SEARCH command finds all the occurrences of a pattern and reports the
addresses where the pattern was found. If the /NOT qualifier is present, the
command reports all addresses in which the pattern did not match.
Format:

SEARCH [qualifier-list] laddress} (pattern} [Imask}]
SEARCH accepts an optional mask that indicates bits to be ignored (don't care
bits). For example, to ignore. bit 0 in the comparison, specify a mask of 1. The
mask, if not present, defaults to O.
A match occurs if (pattern and not mask) =(data and not mask),
where:
Pattern is the target data
Mask is the optional don't care bitmask (which defaults to 0)
Data is the data at the current address

Console Commands 3-13

3.16 START
The START command starts instruction execution at the address you specify.
If no address is given, the current PC is used. If memory mapping is enabled,
macro instructions are executed from virtual memory, and the address is treated
as a virtual address. The START command is equivalent to a DEPOSIT to PC,
followed by a CONTINUE. It does not perform a processor initialization.
Format:

START [{address}]
Arguments:
[a4 dress l

The address at which to begin execution. This address is loaded into the
user's PC.

Example:
»>START 1000

3.17 TEST
The TEST command invokes a diagnostic test program specified by the test
number. If you enter a test number of 0 (zero), all tests that are allowed to be
executed from the console terminal are executed. The console accepts an optional
list of up to five additional hexadecimal arguments.
You can see a full listing of all the tests by running test 9E.
Format:

TEST [(test_number) [(test_arguments)]]

Console Commands 3-19·

Arguments:
{test_number}

A two-digit hexadecimal number specifying the test to be executed.
'lest 9E displays a fun list of all the available tests and their
.
parameters.

{test_arguments}

Up to five additional test arguments. These arguments are
accepted, but the console cannot interpret them.

Example:
>>>TEST 0

3.19 X-Binary Load and Unload
The X command is for use by automatic systems communicating with the console.
The X command loads or unloads (that is, writes to memory or reads from
memory) the specified number of data bytes through the console serial line
(regardless of console type) starting at the specified address.
Format:

X laddress} Icount} CR (line_checksum) (data) (data_checksum)
Arguments:

3-20 Console Commands

{address}
{count}

The address to unload data from or load data to.
Indicates whether to load or unload data, and also indicates the
amount of data to load or unload.
Ifbit 31 of the count is clear, data is received by the console and put
into memory. If bit 31 is set, data is read from memory and sent by
the console. The remaining bits in the count are a positive number
indicating the number of bytes to load or unload.

The console accepts a load or unload command when it receives the
carriage return.

{line_checksum}

The line_checksum is the next byte the console receives. The line_
checksum is not echoed.
The line_checksum is verified by adding all the command
characters, including the checksum and separating space, into
an 8-bit register initially set to zero. The line_checksum does not
include the terminating carriage return, rubouts, or characters
deleted by a rubout. If no errors occur, the result is zero.
If the line_checksum is correct, the console responds with the input
prompt and either sends data to the requester or prepares to receive
data.
If the line_checksum is in error, the console responds with an error
message. This prevents the operator from inadvertently entering
into a mode where the console accepts characters from the keyboard
as data and does not provide an escape mechanism.

{data}

If the command is a load (bit 31 of the count is clear), the console
responds with the input prompt (»», then accepts the specified
number of bytes of data to be put into memory and an additional
byte of received data_checksum. The data is verified by adding all
data characters and the checksum character into an 8-bit register
initially set to zero. If the final content of the register is nonzero,
the data or checksum is in error, and the console responds with an
error message.
If the command is a binary unload (bit 31 of the count is set), the
console responds with the input prompt (»», followed by the
specified number of bytes of binary data. As each byte is sent, it is
added to a checksum register initially set to zero. At the end of the
transmission, the two's complement of the low byte of the register is
sent.
If the data_checksum is incorrect on a load, or if memory or
line errors occur during the transmission of data, the entire
transmission is completed, and the console issues an error message.
If an error occurs during loading, the contents of the memory being
loaded are unpredictable.

{data_checksum}

Console Commands 3-21

The console represses echo while it is receiving the data string and checksums.
The console terminates all flow control when it receives the carriage return at
the end of the command line to avoid treating flow control characters from the
terminal as valid command line checksums.

3.19.1 Controlling the Console Serial Line
You can control the console serial1ine during a binary unload using the control
keys (CtrIlC, CtrllS, CtrllO, and so on). You cannot control the console serial line
during a binary load, because all received characters are valid binary data. The
console has the following timing requirements:
•

It must receive data being loaded with a binary load command at a rate of at

least 1 byte every 60 seconds.
•

It must receive the command checksum that precedes the data within 60
seconds of the carriage return that terminates the command line.

•

It must receive the data checksum within 60 seconds of the last data byte.

If any of these timing requirements are not met, then the console aborts the
transmission by issuing an error message and returning to the console prompt.
The entire command, including the checksum, can be sent to the console as a
single burst of characters at the specified character rate of the console serial line.
The console is able to receive at least 4K bytes of data in a single X command.

3.20 ! (Comment)
The comment character (an exclamation point) is used to document command
sequences. It can be placed anywhere on the command line. All characters
following the comment character are ignored.

Format: !
Example:
»>! The console ignores this line.

1The distances shown in parentheses apply in an uncontrolled environment where heat, humidity, and
temperature may fluctuate.

Creepage distances apply when the module is installed in a controlled
environment. You can check creepage distances by measuring the distance
between adjacent parts.
