Updated: 06/02/2020 by Computer Hope

HyperTerminal is communications software developed by Hilgraeve and is included in Windows 3.x through Windows XP. With HyperTerminal, you can connect and transfer files between two computers using a RS-232 serial cable.

Hyper Terminal

HyperTerminal was widely used by many Windows users to connect to Bulletin Board Systems and today is not as commonly used with the Internet. Although not used today, HyperTerminal can test a computer modem, as well as an alternative for users not connected to the Internet.


HyperTerminal is not included in Windows Vista and later versions of Windows.

How to run HyperTerminal

Windows Vista and later

HyperTerminal is not included in Windows Vista, Windows 7, Windows 8, and Windows 10. However, HyperTerminal Private Edition is available from Hilgraeve for purchase, which is designed to run on Windows Vista through Windows 10.

If you have access to Windows XP, another option to try is the following.

  1. In Windows XP, open Windows Explorer.
  2. Navigate to the C:\Program Files\Windows NT folder and copy the hypertrm.exe file.
  3. Navigate to the C:\WINDOWS\system32 folder and copy the hypertrm.dll file.
  4. Save the copied HyperTerminal files from Windows XP in the same folder paths on the newer computer with Windows Vista or later. The same folder paths should exist and not need to be created.
  5. On the newer computer, double-click the hypertrm.exe file in the C:\Program Files\Windows NT folder to run HyperTerminal.

If HyperTerminal does not run in step 5 above, you may need to run the file in Windows compatibility mode for it to work, see: How to change the Windows compatibility mode.
