Options for device serialPort. SerialOptions
Note: According to the documentation of the Web Serial API, 'baudRate' is a 'required' field as part of serial options. However, we are currently maintaining 'baudRate' as a separate parameter outside the options dictionary, and it is effectively used in the code. For now, we are keeping it optional in the dictionary to avoid conflicts.
