By far the best SCO ANSI emulation I have found on this planet. Just wish they would make a Universal Binary, and add Tabs. Other than that, it is a great terminal emulator. If you are a Unix geek that connects to many, many different types of Unix systems, you need something like this, or you had better be real good at hacking terminfo files. This is the *only* terminal emulator I have found for the Mac that properly emulates SCO Ansi, along with the proper function key mapping.
