This section uses the configuration files of Red Hat 6.7 as an example. Configuration files of other types of OSs may be different.

Use the vi editor to open the /boot/grub/grub.conf file, locate hiddenmenu, and add the following information after hiddenmenu:
```
serial --unit=0 --speed=115200
terminal --timeout=5 serial console
```
Add the following information to the end of the line that contains kernel:
```
consoleblank=600 console=tty0 console=ttyS0,115200n8
```
To enable user root to log in to the BMS through a serial port, add ttyS0 to the end of the security configuration file /etc/securetty.
