Raw COM data

How to test: connect the scale to Windows, confirm it appears under Device Manager → Ports (COM & LPT), select the settings from its manual, click Connect scale, and choose the correct device. Put an item on the scale and watch the raw-data panel. If no data appears, try the scale’s Print/Data button or use its documented request command above.
