It was released as freeware and won the “Online software grand prize 97” competition held by the Japanese tool portal Madonomori in 1997.

It has been popular among engineers in Japan and all over the world for many years, but not being developed since 1998 it slowly started to become out of date. The program got compatibility issues with the latest versions of Windows, was lacking SSH2 protocol support, etc. There were several plug-ins like IPv6 and transparency support developed by different users however they did not address all the issues and could not be distributed as a new version of TeraTerm as this would require permission from Teranishi san who was not easy to reach.

Tera Term sports a clean interface that allows users to perform multiple actions on the go. You are allowed to select the host, and port, and pass one or more commands to the connected Telnet or SSH host.

There are several authentication and encryption modes available for the built-in web server, as you may activate HTTP listening mode, select the IP address and port, and select a connection via HTTP or SSL.
