A terminal emulator, terminal application, or term,[citation needed] is a computer program that emulates a video terminal within some other display architecture. Though typically synonymous with a shell or text terminal, the term terminal covers all remote terminals, including graphical interfaces. A terminal emulator inside a graphical user interface is often called a terminal window.

Console is a terminal emulator and console enhancement for Windows 10 that focuses on direct use and simple interaction. It provides full command-line capabilities, and its straight-forward design hides a significant degree of power and customization.

A terminal window allows the user access to a text terminal and all its applications such as command-line interfaces (CLI) and text user interface (TUI) applications. These may be running either on the same machine or on a different one via telnet, ssh, or dial-up. On Unix-like operating systems, it is common to have one or more terminal windows connected to the local machine.
Terminals usually support a set of escape sequences for controlling color, cursor position, etc. Examples include the family of terminal control sequence standards known as ECMA-48, ANSI X3.64 or ISO/IEC 6429.
Local echo[edit]
Terminal emulators may implement a local echo function, which may erroneously be named 'half-duplex', or still slightly incorrectly 'echoplex' (which is formally an error detection mechanism rather than an input display option).[1][2][3][4]
Line-at-a-time mode/Local editing[edit]
Terminal emulators may implement local editing, also known as 'line-at-a-time mode'. This is also mistakenly referred to as 'half-duplex'.[citation needed] In this mode, the terminal emulator only sends complete lines of input to the host system. The user enters and edits a line, but it is held locally within the terminal emulator as it is being edited. It is not transmitted until the user signals its completion, usually with the âµ Enter key on the keyboard or a 'send' button of some sort in the user interface. At that point, the entire line is transmitted. https://iloveclever491.weebly.com/free-map-drawing-software.html. Line-at-a-time mode implies local echo, since otherwise the user will not be able to see the line as it is being edited and constructed.[1][5] However, line-at-a-time mode is independent of echo mode and does not require local echo. When entering a password, for example, line-at-a-time entry with local editing is possible, but local echo is turned off (otherwise the password would be displayed).[6]
The complexities of line-at-a-time mode are exemplified by the line-at-a-time mode option in the telnet protocol. To implement it correctly, the Network Virtual Terminal implementation provided by the terminal emulator program must be capable of recognizing and properly dealing with 'interrupt' and 'abort' events that arrive in the middle of locally editing a line.[7]
Synchronous terminals[edit]
In asynchronous terminals data can flow in any direction at any time. In synchronous terminals a protocol controls who may send data when. IBM 3270-based terminals used with IBM mainframe computers are an example of synchronous terminals. They operate in an essentially 'screen-at-a-time' mode (also known as block mode). Users can make numerous changes to a page, before submitting the updated screen to the remote machine as a single action.

Terminal emulators that simulate the 3270 protocol are available for most operating systems, for use both by those administering systems such as the z9, as well as those using the corresponding applications such as CICS.

Other examples of synchronous terminals include the IBM 5250, ICL 7561, Honeywell Bull VIP7800 and Hewlett-Packard 700/92.
Virtual consoles[edit]
Virtual consoles, also called virtual terminals, are emulated text terminals, using the keyboard and monitor of a personal computer or workstation. The word 'text' is key since virtual consoles are not GUI terminals and they do not run inside a graphical interface. Virtual consoles are found on all GNU/Linux systems, even on systems which don't have a desktop environment or graphical system installed. They are primarily used to access and interact with servers.
Examples of terminals emulated[edit]Free Terminal Emulator
Many terminal emulators have been developed for terminals such as VT52, VT100, VT220, VT320, IBM 3270/8/9/E, IBM 5250, IBM 3179G, Data General D211, Hewlett Packard HP700/92, Sperry/Unisys 2000-series UTS60, Burroughs/Unisys A-series T27/TD830/ET1100, ADDS ViewPoint, Sun console, QNX, AT386, SCO-ANSI, SNI 97801, Televideo, and Wyse 50/60. Additionally, programs have been developed to emulate other terminal emulators such as xterm and assorted console terminals (e.g., for Linux). Finally, some emulators simply refer to a standard, such as ANSI. Such programs are available on many platforms ranging from DOS and Unix to Windows and macOS to embedded operating systems found in cellphones and industrial hardware.

The terminal is the beating heart of Linux, no matter how hard todayâs user-friendly graphical distros might try to push it into the background. If you need something done quickly and efficiently, itâs likely that the best way to do it is with some complex keyboard wrangling. Exactly what to type is beyond the scope of this article â check out the guide here to get yourself started on that front.
Putty Serial Terminal Emulator
The key, if youâre a terminal-slinging Linux badass, is to make sure you type those commands with as much style and panache as possible. And while youâll likely never be in a position where youâre not able to drop to a straight full-screen shell, having a quick window to the command line on your desktop is always handy.
Of course, your Linux distro will have a âTerminalâ application already such as xterm, Gnome Shell or Konsole â but this probably isnât as good as your emulator could be. Letâs refresh your view of those plain old white-on-black characters, as we pick out our top six Linux Terminal emulators.
1. Cool Retro Term
If you have a bunch of CPU cycles and graphics processing power that needs using up, youâre sure to get a kick out of Cool Retro Term. It emulates the look of a really old-school cathode ray monitor, complete with phosphorous glow, burn-in, and bloom around the characters. If you cut your teeth with the monochrome screens of the early eighties, this is a nostalgic (and highly customisable) trip back to the past.
You can even select between a number of character sets, evoking memories of (for example) the all-caps Apple II, as well as selecting between a number of colours to replicate the amber warmth of classic Zenith monitors, or a rarely-used but nonetheless beautiful cyan.
While the usefulness of some of its features is questionable â particularly the optional screen jitter replicating a slightly dodgy signal cable, and some of the older fonts â Cool Retro Term (CRT) is a beautiful toy to play with.
2. Guake
This Terminal emulator, crafted specifically for Gnome, takes inspiration from the classic shooter Quake, as its name suggests. Guake doesnât offer you quad or mega-health power-ups, red armour, or even come branded with Quakeâs classic brown-on-brown colour scheme, thankfully. Instead, it apes the behaviour of Quakeâs console, un-hiding itself and dropping down from the top of the screen when you hit a hotkey.
This behaviour is highly useful, particularly when youâre working with a small screen. Thereâs no need to keep a window open, hunt around for the Terminal icon when you need to type something useful, or check your performance in htop. Just tap [F12] to bring it down, or [F11] to make it full-screen, and youâre away.
Guake also comes with a selection of neat colour schemes, giving you a few stylish options. There are similar options for other desktops, too: check out the likes of YaKuake for KDE or the GTK-based tilda.
3. Terminator
How much street cred does a single Terminal window actually afford you? Every command line warrior worth his or her salt is jumping between a number of different sessions for different tasks, has one eye on htop (or similar) at all times to manage system resources, and so on.
There are actual shell-based options for this â GNU Screen, for example, or tmux â and Gnome Terminal allows you to open extra tabs and flick between them. But Terminator, which borrows much of its code from Gnome Terminal and tends to update as soon as its parent does, splits up your different sessions into individual panes within a single Terminal app.
This means you can have everything open and available at one time â keep an eye on stats, watch a text-mode clock like vtclock, edit docs in nano, run whatever commands you need, all from one grid interface which can be tweaked as your needs require.
4. Terminology
Some people lean on the Terminal as their default method of Linux navigation, which can be a little restrictive. Normally youâd hunt down a file, then have to jump to a graphical desktop application to preview it, unless it's a plain text document. That isn't the case with EFL-based Terminology, an app which celebrates the Terminal while doing away with its more irritating old-school features.
Files, URLs and email addresses can be automatically previewed in Terminologyâs window. Click an image, or a video, and youâll be shown a preview within the Terminal itself. It supports panes (known as âsplitsâ) in much the same way as Terminator, and can be customised. Why not apply an individual background image or colour scheme to each split, or fiddle with the transparency for that late nineties âlook what Linux can doâ vibe?
The options are all there, with text mode triggers and a vast number of settings tucked away in its context menus.
5. st (simple terminal)
One of Linuxâs big problems is that it sometimes does a bit too much. Your chosen Terminal emulator is probably compatible with a whole raft of obscure, archaic and/or unused commands.
This can become very messy as Linux code tends to pass through a lot of hands before being released. It doesnât have to be that way, though: st is a simple Terminal emulator that does precisely what itâs meant to do and little else.
Donât make the mistake of thinking itâs all that simple, though, despite the name (st stands for Simple Terminal). Thereâs still support for all the colours you could ask for, clipboard handling, a full UTF-8 character set, and a lot of font customisation options including antialiasing.
If youâre not one for Terminal frippery and would prefer a more straightforward environment, this is most definitely the one for you. 2019 ford fiesta manual transmission.
6. rxvt-unicode
Also known as urxvt, this is the Terminal emulator which many veteran Linux users end up going with. Not because it has pretty graphics or gimmicks, but due to the fact that itâs absolutely rock solid and free of glitches.
Thatâs not to say it doesnât do fancy things: it supports colours, unicode, customisable fonts with italics and bold if required, and even transparency. The main program runs as a daemon, meaning it neatly conserves system resources when youâre running multiple windows over multiple desktops.
Itâs very difficult to cause rxvt-unicode to crash, and thatâs its main selling point â even if youâre playing with a more visual Terminal program, having this installed for when itâs time to get serious is a clever choice.
