  1. Use the vi editor to open the /etc/default/grub file and add the following information after the GRUB_CMDLINE_LINUX field.
    consoleblank=600 console=tty0 console=ttyAMA0,115200
  2. Run the following commands to update the configuration:

    stty -F /dev/ttyAMA0 speed 115200

    grub2-mkconfig -o /boot/efi/EFI/euleros/grub.cfg

    systemctl enable serial-getty@ttyAMA0

  3. To allow user root to log in to the BMS using a serial port, check whether the /etc/securetty configuration file contains ttyAMA0. If not, add it.
