v
In the command-line interface, the output buffer limit is 2 KB. There is no
buffering. The output of an individual command cannot exceed 2048 characters.
This limit does not apply in serial redirect mode (the data is buffered during
serial redirect).
v
The output of a command is displayed on the screen after the command has
completed execution. This makes it impossible for commands to report real-time
execution status. For example, in the verbose mode of the flashing command,
the flashing progress is not shown in real time. It is shown after the command
completes execution.
v
Simple text messages are used to denote command execution status, as in the
following example:
system> power on
ok
system> power state
Power: On
State: System power off/State unknown
system>
v
The command syntax is case sensitive.
v
There must be at least one space between an option and its argument. For
example, ifconfig eth0 -i192.168.70.133 is incorrect syntax. The correct
syntax is ifconfig eth0 -i 192.168.70.133.
v
All commands have the -h, -help, and ? options, which give syntax help. All of
the following examples will give the same result:
system> power -h
system> power -help
system> power ?
v
Some of the commands that are described in the following sections might not be
available. To see a list of the commands that are supported, use the help or ?
option, as shown in the following examples:
