+- On Windows, if the terminal is closed without first closing the IDF Monitor, some drivers may not release the serial port. To release the port, you may need to unplug and replug the USB cable, or in some cases even restart the computer. This issue has been observed with the CH9102 USB-to-UART bridge. Other drivers, such as CP210x and CH340, should work fine.
+
+  To prevent this issue, make sure to close the IDF Monitor properly before exiting the terminal, or consider using an alternative USB-to-UART bridge.
