How Can I Reliably Read and Display Data from a Scale via USB Serial Port, Handling Connection Issues?

This application utilizes a serial port helper class to connect to a scale through a USB serial port adapter. It manages various port settings and displays the received scale data within a text box. The code also includes functionality to identify available COM ports. A key feature addresses the problem of question marks appearing in the displayed data, often caused by communication errors.

The solution employs a custom event handler to process incoming serial data. This handler reformats the data before displaying it in the text box, adapting to the specific data format of the scale.

The application further enhances reliability by monitoring device connection changes. Upon detecting a new device, it updates COM port settings and re-establishes the connection. Conversely, when a device is removed, the serial port connection is closed, releasing resources.

This improved approach offers a more stable and user-friendly interface for interacting with the scale via a USB serial port adapter.
