A terminal emulator is an application whose window provides a command-line interface to your system--for example, operating system commands, script names, or commands that run applications.
All applications have a command that you can type to start them. The application's documentation usually describes how to use the command.
The desktop provides a terminal emulator called dtterm. Your system may include other terminal emulators. To open a terminal emulator window, click the This Host control in the Hosts subpanel.
For more information on using dtterm, see Chapter 12, Using Terminal .
