I have had a brief play with it and it works as described as far as I can see

Direct access to hardware interfaces such as serial ports increases the attack surface of the browser, since malicious sites could interact with connected devices. Also a risk is that direct access to serial ports allows a website to identify and track a user through their connected devices. Each device exposes hardware identifiers or behaves in a unique way, which can be used for fingerprinting. In practice, this means a site could recognize a user even if they change IP addresses, clear cookies, or browse in private mode.

Looks good, created 3 feature requests

- X-Y plot
- logarithmic scaling
- import of saved CSV data to view.
