In this case, we have to make use of a serial terminal like CoolTerm to perform tests on data transmitting and receiving.
This will help us to ensure that everything is working as expected.
Compared to parallel communication (4, 8 or 64-bit), serial communication is popular in embedded systems due to low cost and effective long-distance transmission.įor makers and engineers, we sometimes need to monitor the data that is transmitted between our devices and computer. Serial communication continues to be used all around us today. If you are unfamiliar with serial communication and want to know more, please visit our detailed beginner’s guide – RS232 vs TTL: Beginner Guide to Serial Communication. In contrast, parallel communication sends several bits as a whole, through a few parallel channels. What makes serial communication distinct is that data is sent sequentially one bit at a time through a single channel.
What is Serial Communication?Īs you might have guessed, serial communication is used to send and receive data to peripheral devices. This makes CoolTerm a popular and affordable option for users who need a convenient and effective serial terminal software solution. CoolTerm is a user-friendly terminal for serial communication with hardware that has been connected to your computer via serial ports.ĬoolTerm is freeware/donationware developed by Roger Meier, and is available for Windows / Mac / Linux devices.
