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;

Utilize the partial online help. That is, when you enter
an incomplete keyword and the Tab key, if the input
keyword uniquely identifies an existing keyword, the
system completes the keyword and displays the
command on the next line. If the input keyword
matches more than one keyword, press the Tab key
repeatedly, all the keywords are displayed on the
terminal screen, with each keyword on a line. If the
input keyword matches no keyword, the system
displays your original input on a new line without any
change.
