4. 要启用多个 GRUB 选项来通过 RAC 串行连接启动虚拟控制台会话，将以下行添加到所有选项：
console=ttyS1,115200n8r console=tty1
本例显示 console=ttyS1,57600 添加到第一个选项。
注: 如果引导加载程序或操作系统可以提供串行重定向，如 GRUB 或 Linux，则 BIOS 引导后重定向设置必须禁用。这可避免
多个组件访问串行端口的潜在混乱情况。
允许在引导后登录到虚拟控制台
在文件 /etc/inittab 中，新增一行以在 COM2 串行端口上配置 agetty：
co:2345:respawn:/sbin/agetty -h -L 57600 ttyS1 ansi
以下示例显示带有新增行的示例文件。
#inittab This file describes how the INIT process should set up
#the system in a certain run-level.
#Author:Miquel van Smoorenburg
#Modified for RHS Linux by Marc Ewing and Donnie Barnes
#Default runlevel. The runlevels used by RHS are:
#0 - halt (Do NOT set initdefault to this)
#1 - Single user mode
#2 - Multiuser, without NFS (The same as 3, if you do not have #networking)
#3 - Full multiuser mode
#4 - unused
#5 - X11
#6 - reboot (Do NOT set initdefault to this)
