Hello everyone! Today I am sharing the Serial Terminal software developed in Visual Basic 2010. It provides a simple window for opening a COM port, sending text, and viewing received data in character, hexadecimal, decimal, and binary forms. We will download the original package and work through a practical communication session. The earlier Visual Basic serial-port tutorial introduced basic transmission and reception. This terminal adds convenient display tabs and optional carriage-return and line-feed characters. Those small features are useful when a microcontroller appears to receive your command but does not respond as expected. We will explain the original interface as it is shown, then cover connection settings, line endings, data representation, and troubleshooting. The download re ...
Hello friends, I hope you are doing well. In this tutorial, we will build a simple serial terminal in Visual Basic 2010. The application will detect the COM ports available on a Windows computer, open a selected port, transmit text, receive incoming data and close the connection cleanly. This article keeps Visual Basic 2010 because that is the environment used in the original project and screenshots. According to the official Microsoft lifecycle record , Visual Studio 2010 reached the end of support in July 2020, so you should use a supported Visual Studio and .NET version for a new production application. However, the serial communication principles explained here still apply to maintenance work, laboratory computers and older engineering projects. We will begin with the electrical and pr ...
