Free terminal emulator


Tera Term is a free, open-source, software-based terminal emulator application. The tool emulates several different categories of computer terminals, ranging from DEC VT100 to DEC VT382. Tera Term supports SSH 1 & 2, telnet, and serial port connections. Also, it has an embedded macro scripting language along with several other nifty plugins.

The clean interface lets you perform multiple actions effortlessly and on the go. You’re allowed to choose the host and port, as well as pass one or multiple commands to the connected SSH or Telnet host.

You’ll find a range of encryption and authentication modes available for the embedded web server. You can activate HTTP listening mode, choose the IP and port, and pick a connection via SSL or HTTP.

Moreover, you can incorporate a certificate name and password file, enable incoming requests, allow the creation of status reports, and choose a remote connection/ disconnection. You can export the results and error log to HTML.

Because Tera Term acts as a facilitator between web-based app servers and any remote SSH/Telnet host, you can utilize this tool to regulate and monitor any program with a Telnet-based interface.

Tera Term is a highly useful app that allows the connection to remote SSH/Telnet hosts. The crisp and clean layout makes it easier to operate with.
