MacTerm
Powerful replacement for macOS Terminal, supporting 24-bit color, standard graphics protocols and iTerm2 image sequences and color schemes. MacTerm is one of the few emulators in the world that allow terminal-based programs to set up to 8 bits per RGB component (for a total of 24 bits), allowing for a large number and large spectrum of colors on the screen. The terminal is capable of preserving incoming text perfectly: whether you copy it to the Clipboard, capture it to a file, print it, or drag and drop, any special characters will be present. You can also use the floating command line window to input any kind of character. (In 4.1.0, there are limits on which Unicode characters can actually be displayed by the terminal; these limitations are being removed in 5.0.) Finally, Unicode is supported for file names, preference collection names, and macros.

MacWise
MacWise emulates ADDS Viewpoint, Wyse 50, Wyse 60, Wyse 370, Televideo TV 925, DEC VT100, VT220, and Prism terminals. Supports ANSI and SCO ANSI color. Esprit III color is also supported in Wyse 370 mode. MacWise allows a Macintosh to be used as a terminal, connected to a host computer directly, by modem, local area network, or over the Internet with telnet or ssh secure shell. The emulators support video attributes such as dim, reverse, underline, 132-column modes, protected fields, and graphic characters sent from the host computer, as well as enhanced Viewpoint mode. Features include a phone list and dialer for modems, on-screen programmable function keys, connection scripts, and more. Works with desktop Macs, MacBooks and PowerBook. You can scroll back to the past 50 pages of data. MacWise remembers the last 50 pages that appear on your screen, regardless of whether the data has scrolled across the screen or the screen has cleared.

PuTTY
PuTTY is a free implementation of SSH and Telnet for Windows and Unix platforms, along with an xterm terminal emulator. PuTTY is a client program for the SSH, Telnet, Rlogin, and SUPDUP network protocols. These protocols are all used to run a remote session on a computer, over a network. PuTTY implements the client end of that session, the end at which the session is displayed, rather than the end at which it runs. In really simple terms, you run PuTTY on a Windows machine, and tell it to connect to (for example) a Unix machine. PuTTY opens a window. Then, anything you type into that window is sent straight to the Unix machine, and everything the Unix machine sends back is displayed in the window. So you can work on the Unix machine as if you were sitting at its console, while actually sitting somewhere else. All of PuTTY's settings can be saved in named session profiles. You can also change the default settings that are used for new sessions.
