QSerial is a graphical serial port utility for communicating with connected hardware. It provides controls for configuring serial connections, transmitting data in different formats and inspecting responses from external devices.
One of its distinguishing capabilities is support for several USB-to-serial adapters without requiring a corresponding kernel-mode driver. These include devices based on Silicon Labs CP210x, WCH CH34x and Prolific PL2303x controllers.
QSerial also offers flexibility when working with equipment that uses different character encodings or binary communication formats. Outgoing data can be entered as ordinary text or encoded values, while incoming traffic can be decoded using selectable character sets or examined in hexadecimal form.
The application concentrates on serial communication rather than graphical telemetry analysis. It is therefore most useful for sending test commands, examining device responses and diagnosing communication problems.
This is free and open source software.
Key Features
