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.
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.
