Entering Console Commands
This section describes the conventions to follow when you enter
console commands.
Rules for Entering Console Commands
You can use console commands when the system monitor
displays the
>>
or
R>
prompt. When the system displays the
R>
prompt, you can use only the boot and passwd commands until
you enter the console command password.
Follow these rules when you type console commands:
Type uppercase and lowercase letters exactly as they
appear in command lines. The system treats uppercase and
lowercase letters as different input.
Press Return after you type a command.
Enter numbers as follows:
Enter decimal values as a string of decimal digits with
no leading zeros (for example, 123).
Enter
octal values as a string of octal digits with a
leading zero (for example, 0177).
Enter
hexadecimal values as a string of hexadecimal
digits preceded by 0x (for example, 0x3ff).
When reading or writing to memory, enter data as bytes,
halfwords, or words. Because a word is 4 bytes, successive
addresses referenced by a word are successive multiples
of 4. For example, the address following 0x80000004 is
0x80000008. An error occurs if you specify an address that
is not on a boundary for the data size you are using.
The following key combinations have an immediate effect
when the system is in console mode:
Ctrl-s freezes the screen display.
Ctrl-q releases a frozen screen display.
Ctrl-c aborts a command.
Ctrl-u erases a partially typed command line.
