You can follow the steps in my technical blog. This will explain how to add Hyperterminal back into Vista.This works for both 32/64bit Vista.

While Hyperterminal shipped with Windows XP, it however did not ship with Windows Vista (Boo Microsoft, Boo!). However that doesn’t mean that you can’t use it. What you can do is rip the following files from a Windows XP disc or installation;
hypertrm.dll
hypertrm.exe
Now all you need to do is place them anywhere in your Vista directory and link the shortcut to
hypertrm.exe. Now you can launch it and it will first ask for Zip code and state. Afterwards you can being to use Hyperterminal as usaual. If you don’t have a copy of Windows XP handy, you can download the file’s I’ve ripped and use it as well;

Side note, although I am using the Windows 7 RC1, I do see a placeslot of Hyperterminal, but no application for it. You’ll be happy to know that this also will work for Windows 7 as well ;)
