30 CHAPTER 1: CLI OVERVIEW
Terminal Display CLI provides the following display feature:
■ Display suspending. That is, the displaying of output information can be split
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 6 lists 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.
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.
Command Edit The CLI provides basic command edit functions and supports multi-line editing.
The maximum number of characters a command can contain is 254.
Table 8 lists
