nfortunately, Hyperterminal is not included with Windows 7 but you can still control your serial devices with alternate methods. There are several alternatives to this which i am going to discuss in this guide. By the end, you will know how to set one up and which one to use. Why is it not included with Windows 7 is a question for Microsoft and they have the answer HERE
Alternative #1 PuTTy
PuTTy is an awesome FREE and opensource emulator that has been around for 16 years. You can download PuTTy from http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
How to use putty as Hyperterminal
You will need to have a COM port on your machine whether laptop or desktop in order to connect your console cable first. If you do not have one, then USB port is basically available on almost all computers so you would need a DB9 to USB Converter – Assuming you now have the converter/port, you will connect one end to your device and the other end to DB9 which goes into USB port on your computer, or if you have a com port, then connect directly.
You now need to have the com port number, which you can get from Device Manager -> Ports (COM & LPT)
Once you have it, you will then start to Configure PuTTy with your Console Settings
Open PuTTy and click Serial from the left pane which is the last option. This is where you will conf. your terminal settings: eg for a Cisco router, this will look like this:
Now click the Session button in left pane, the first option and select Open.
.
This will get you connected to your device and you will be using PuTTy as your Hyperterminal
Installing Hypterterminal on Windows 7
Now, if you still do not want to use PuTTy and have Hypterterminal back, then here’s what you will need to do.
In order to do this, you will need to have access to a Windows XP computer from where you can copy the three files we need:
C:\Program Files\Windows NT\hypertrm.exe
C:\WINDOWS\system32\hypertrm.dll
C:\WINDOWS\Help\hypertrm.chm
Once you have the above files copied then create the folders on your Windows 7 as follows and copy the three files into them.
For a 32-bit Windows 7 create a folder
C:\Program Files\HyperTerminal
For a 64-bit Windows 7 create a folder
C:\Program Files (x86)\HyperTerminal
Now from the folders, you can create a shortcut for hypertrm.exe and run it to get HyperTerminal back OR if you wish to get HyperTerminal on Start Menu, then put the hypertrm.exe file in C:\ProgramData\Microsoft\Windows\Start Menu\Programs
