Launch the software. It will auto-detect the COM port (e.g., COM3). If not, manually select the port from Device Manager.

Relying on this software for health decisions can be dangerous. False positives (indicating a disease that does not exist) can cause unnecessary panic. False negatives (missing actual conditions) can delay necessary medical treatment.
