4.2 Keyboard-Command Summary
Table 4-4 below and on the next page summarizes the commands that can be sent
to the ServSwitch. To enter any command at the shared keyboard, first press and
release the left Control key, represented by “[Ctrl].” (This cues the Switch to look
for commands from that keyboard.) Then enter the command followed by any
arguments you wish to specify (the port number, for example).
Letter commands are not case-sensitive; they are all shown in uppercase for
clarity only.
When you enter numeric commands or arguments, use only the numbered keys
at the top of your alphanumeric keyboard. Numbers entered from the numeric
keypad to the right will not be recognized as valid commands.
All of these commands have a two-second timeout between characters. This
means that if you begin entering a command, but you stop for more than two
seconds at any time before you type the final character, the command is aborted
and the ServSwitch returns to normal operation. This keeps the Switch from
getting stuck waiting for you to finish the command.
The [Ctrl] character is always passed through to the CPU. The command
characters and operands, however, are absorbed by the ServSwitch and are not sent
to the CPU.
Many of these commands have factory-default values (see
Appendix A
) that can
be reloaded if your Switch becomes badly misconfigured; see
Section 6.1
.
