ICS Prompts
ICS uses the SSU-2000 name followed by command prompt. The prompt is either
+>
or
->
:
The
+>
prompt indicates that the last output string is an event.
The
->
prompt indicates that the last output string is a response to a command or
end-of-line.
Line Editing
The ICS interface supports these line-editing functions:
Press ESC (Escape) to clear the ICS command buffer.
Press the Backspace key to delete the last character entered.
Press Ctrl + C to stop all output and flush the transmit buffers.
Input and output end-of-line (EOL) characters function independently. The ICS
interface automatically adjusts to changes in incoming EOLs.
Logon Requirements
The ICS interface features an optional logon requirement:
If the user list is empty and no passwords have been set for default users, logon
is not required and the software defaults to the Administrator user.
After a user name has been added or a password has been entered for the
Administrator user, a user name and logon password is required.
While communicating with the SSU-2000 using an EIA-232-C connection, if the
communications port requires a user name and logon password, only these
commands are available until an operator logs on: ID, INFO, LOGIN, HELP, and
DOY. In this state, the port displays autonomous events but does not allow a
query of event history until the operator logs on.
While communicating with the SSU-2000 using Telnet, if the communications
port requires a user name and password to log on, the interface does not allow
commands to be performed or events to be displayed until the operator logs on.
For example, events are stored in the event history but are not displayed on ports
to which no user is logged on.
