| Issue | Solution | | :--- | :--- | | "Access Denied" / Port in Use | Another program (Arduino IDE, Cura, another terminal) is using the port. Close the other program. | | Garbage Text (ÿýÿý) | The Baud Rate is incorrect. Try changing from 9600 to 115200 (or vice versa). | | Cannot open port | The driver is missing. Check Device Manager. If you see "Unknown Device", you need to install drivers (usually CH340 for cheap Arduino clones). | | Chinese Characters | If the interface is in Chinese, look for a language setting (often a dropdown in the menu bar or a "Setup" -> "Language" option). |

Overall Rating: ⭐⭐⭐⭐☆ (4.5/5)
