These terminals came in many form factors, but they soon began to resemble what would become their personal computer descendants. 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. Back when computers where big, bulky, and took up entire rooms, there were only a handful of ways to interface with them. To understand the use of the word terminal, we must visit the not so distant past.

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.

In this tutorial we will discuss what a terminal is, which terminal programs are best suited for certain situations and operating systems, and how to configure and use each program. There are lots of different terminal programs out there, and they all have their pros and cons. Once you have learned the ins and outs of a terminal application, it can be a very powerful tool in your electronics and programming arsenal. They allow you to see data sent to and from your microcontroller, and that data can be used for a number of reasons including troubleshooting/debugging, communication testing, calibrating sensors, configuring modules, and data monitoring.

In short, serial terminal programs make working with microcontrollers that much simpler. This tutorial is here to help you understand what these terms mean and how they form the larger picture that is serial communication over a terminal.

For someone who isn't familiar with these terms and the context in which they are used, they can be confusing at times. These are all words that get thrown around a lot when working with electronics, especially microcontrollers.

Arduino Serial Monitor (Windows, Mac, Linux)ĬOM ports.

It's as simple as it gets! The tool is free and is also available for other popular operating systems besides Windows.Serial Terminal Basics a tutorial The bottom right corner also contains a couple of signalization lights to let you know about the current state of the connection. Current connection settings can be saved for future use if you are regularly working with similar devices. The view can be switched between ASCII and hexadecimal and you can easily clear data, connect and disconnect from the current connection, and open new terminals.

More advanced users will immediately know how to edit a few settings to really accommodate the tool to their special needs. It automatically chooses one of the ports by default but you can change it in the Options window.Įverything related to the communication can be set up in Options, including baudrate, stop bits, capture format, the form of the termination string, and many more. When you start the app, you are presented with nothing but a terminal where you can immediately start entering data to be sent to one of the serial ports. Luckily, there exists a tool which can make the process a whole lot easier.ĬoolTerm is a simple serial port communication tool which can be enjoyed by both professionals and casual users if they need to exchange data with a device connected to some of the serial ports attached to your PC. Price: $ Communicating with devices connected to serial ports on your computer is often a complicated job but it's often a must when it comes to connecting to microcontrollers, servo controllers, robotic kits, etc.
