Terminal emulators go by many names, and, due to the varied use of the word terminal, there can often be some confusion about what someone means when they say terminal. Let’s clear that up. Brief History. To understand the use of the word terminal, we must visit the not so distant past.
Back when computers where big, bulky, and took up entire rooms, there were only a handful of ways to interface with them. Punch cards and paper tape reels where one such interface, but there was also what was known as a terminal that was used for entering and retrieving data. These terminals came in many form factors, but they soon began to resemble what would become their personal computer descendants. Many consisted of a keyboard and a screen.
Terminals that could display text only were referred to as text terminals, and later came graphical terminals. When discussing terminal emulators, it’s these terminal of days past that are being referenced.

Serial communication terminal alternatives for windows.
An OG terminal. Modern Terminals. Today, terminal programs are “emulating” the experience that was working on one of these terminals. They are known as emulators, applications, programs, terms, TTYs, and so on. For the purposes of this tutorial, just the word terminal will be used. Many terminals use to emulate specific types of computer terminals, but today, most terminals are more generic in their interface.
When working on a modern operating system, the word terminal window will often be used to describe working within one of these applications. And, often, when reading other tutorials and hookup guides, you will be requested to open a terminal window.
Just know that means to open whichever one of these terminals programs strikes your fancy. It is also worth noting that many terminal programs are capable of much more than just serial communication. Many have network communication capabilities such as telnet and SSH. However, this tutorial will not cover these features.
Terminal vs Command Line. A terminal is not a command prompt, though the two are somewhat similar.
In Mac OS, the command prompt is even called Terminal. Hence the confusion when using that word. Regardless, you can perform some of the same tasks in a command prompt that you could also perform within a terminal window, but it doesn’t work the other way around; you cannot issue command line statements within a terminal window. We will go over how to create a serial terminal connection within a command line interface later in this tutorial. For now, just know how to distinguish between the two. Basic Terminology Here are some terms you should be familiar with when working within a serial terminal window.
Many of these terms are covered in a lot more detail in our Serial Communication tutorial. It highly recommended that you read that page as well to get the full picture. ASCII - Short for the American Standard Code for Information Interchange’s character encoding scheme, ASCII encodes special characters from our keyboards and converts them to 7- bit binary integers that can be recognized by a number of programs and devices. ASCII charts are very helpful when working with serial terminals. Baud Rate - In short, baud rate is how fast your data is being transmitted and received.
Just remember that all the links in your chain of communication have to be “speaking” at the same speed, otherwise data will be misinterpreted on one end or the other. Transmit (TX) - Also known as Data Out or TXO. The TX line on any device is there to transmit data. This should be hooked up to the RX line of the device with which you would like to communicate. Receive (RX) - Also known as Data In or RXI. The RX line on any device is there to receive data.
This should be hooked up to the TX line of the device with which you would like to communicate. COM Port (Serial Port) - Each device you connect to your computer will be assigned a specific port number. This helps to identify each device connected. Once a device has a port assigned to it, that port will be used every time that device is plugged into the computer. Your device will show up on your computer as either COM# (if you. Much like terminal is synonymous with the terminals of old, so too is teletype. These were the electromechanical typewriters used to enter information to the terminal and, thus, to the mainframe.
When working with terminals on Mac and Linux, you will often see tty used to represent a communication port rather than . These formats can vary, and the settings of your terminal can be adjusted accordingly to work with different packet configurations. One of the most common configurations you’ll see is 8- N- 1, which translates to 8 data bits, no parity bit, and one stop bit. Flow Control - Flow control is controlling the rate at which data is sent between devices to ensure that the sender is not sending data faster than the receiver can receive the data.
In most applications used throughout these tutorials, you will not need to use flow control. The flow control may also be present in the shorthand notation: 8- N- 1- None, which stands for no flow control. Carriage Return & Line Feed - Carriage return and line feed are the ASCII characters sent when you press the enter key on your keyboard. These terms have roots from the days of typewriters. Carriage return meant the carriage holding the paper would return to the starting point of that particular line.
Line feed (aka new line) meant the carriage should move to the next line to prevent typing over the previous line. When typing on a modern keyboard, these terms still apply. Every time you press enter (or return) you are telling your cursor to move down to the next line and move to the beginning of that new line. Consulting our handy- dandy ASCII table, we can see that the character for line feed is 1.
A in hex) and carriage return is 1. D in hex). The importance of these two characters cannot be stressed enough.
When working in a terminal window you’ll often need to be aware of which of these two characters, if not both, are being used to emulate the enter key. Some devices only need one character or the other to know that a command has been sent. More importantly, when working with microcontrollers, be aware of how you are sending data. If a string of 5 characters needs to be sent to the micro, you may need a string that can actually hold 7 characters on account of the 1. Local Echo - Local echo is a setting that can be changed in either the serial terminal or the device to which you are talking, and sometimes both.
This setting simply tells the terminal to print everything you type. The benefit from this is being able to see if you are in fact typing the correct commands should you encounter errors. Be aware, though, that sometimes local echo can come back to bite you. Some devices will interpret local echo as double type. For example, if you type hello with local echo on, the receiving device might see hheelllloo, which is likely not the correct command. Most devices can handle commands with or without local echo.
Just be aware that this can be an issue. Serial Port Profile (SPP) - The Serial Port Profile is a Bluetooth profile that allows for serial communication between a Bluetooth device and a host/slave device. With this profile enabled, you can connect to a Bluetooth module through a serial terminal. This can be used for configuration purposes or for communication purposes. While not exactly pertinent to this tutorial, it’s still good to know about this profile if you want to use Bluetooth in a project. Connecting to Your Device.
Now that you know what a terminal is and the lingo that comes with the territory, it’s time to hook up a device and communicate with it. This page will show you how to connect a device, how to discover which port it has been assigned, and how to communicate over that port. What You’ll Need. For this example you’ll need. Discovering Your Device. Once you have all your supplies ready, attach the FTDI Basic to the USB cable, and attach the cable to your computer. If this is the first time you’ve plugged in a device of this nature into your computer, you may need to install the drivers.
If this is the case, visit our FTDI Driver Installation Guide. If the drivers are all up to date, carry on. Depending on which operating system you’re using, there are a few different ways to discover which port your device has been assigned. Device Manger (Windows)No matter which version of Windows you have, you have a program called Device Manger. To open device manger, open the start menu, and typedevmgmt. Press enter, and it’ll open right up.
