Rules for Typing Console Commands
Use console commands when the system monitor displays the
prompt >> or R>. Follow these rules:
Type uppercase and lowercase letters exactly as they
appear in command lines. The system recognizes uppercase
and lowercase letters as different input.
Press Return after typing a command message.
Enter number values 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, you have a choice
of data sizes: byte, halfword, or word. 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 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.
DEL deletes the last character typed.
