This app talks to the VetHDO device over the Web Serial API, which is only available in Chromium-based browsers (Google Chrome / ChromeOS) over a secure (HTTPS) connection.
Please open this page in Google Chrome on the clinic's ChromeOS device.
This app is already running in another browser tab or window. Only one tab can talk to the VetHDO device at a time, so this tab has been left inactive to avoid contending for the serial port.
Please switch to the tab that is already open, or close it and reload here.
