In Linux, accessing a serial port device requires the appropriate permissions. If your C++ program does not have sufficient permissions to access the serial port device, you will get a "Permission denied" error.

To solve this error, you can use the following command to add the current user to the dialout group:

sudo usermod -a -G dialout $USER

After adding the user to the dialout group, you need to log out and log back in for the changes to take effect.
