Terminal Display 7
Enter a command, the first several characters of an available keyword which uniquely
identifies the keyword, and press <Tab>, to complete the keyword will be
automatically completed.
Terminal Display CLI provides the following display feature:
■ Display suspending. That is, the displaying of output information can be paused
when the screen is full and you can then perform the three operations listed in
Table 5 as needed.
Command History CLI can store the latest executed commands as history commands so that users can
recall and execute them again. By default, CLI can store 10 history commands for
each user. Table 6lists history command-related operations.
As the Up and Down keys have different meanings in HyperTerminal running on
Windows 9x, these two keys can be used to recall history commands only in terminals
running Windows 3.x or Telnet running in Windows 3.x. You can press <Ctrl+P> or
<Ctrl+N> in Windows 9x to achieve the same purpose.
If you enter and execute the same command successively for multiple times, only the
first command is buffered.
Error Messages If the command you enter passes the syntax check, it will be successfully executed;
otherwise an error message will appear. Table 7 lists the common error messages.
