HyperTerminal is a Windows XP application. But Windows Vista or Windows 7 do not include this application. I will tell you how to install the HyperTerminal client on Windows Vista or Windows 7.
Please Download below file.
Now you need to extract the file and copy files to following path
C:\Program Files\Windows NT\hypertrm.exe
or keep the files hypertrm.dll and hypertrm.exe in the same folder
Now just run hypertrm.exe and HyperTerminal is on Windows 7.
If you want to have HyperTerminal on your Start Menu just create a shortcut to hypertrm.exe and put it in " C:\ProgramData\Microsoft\Windows\Start Menu\Programs " and when you go to All Programs under the Start Menu HyperTerminal will be there.
