-> EMS Console -> Disabled (default)
2. Software Configuration.
1) RHEL OS의 Grub Configure (커널 파라메터 추가, 뒤에 나열된 터미널이 주 콘솔)
# vim /boot/grub/grub.conf
------------------------------------------
# ttyS0 and unit 0 are for com1 and ttyS1 and unit 1 are for com2.
# rear is primary display
console=tty0 console=ttyS1,115200
------------------------------------------
e.g.)
------------------------------------------
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu

2) check teminial in list (목록에 있는지 검토)
# /etc/securetty
------------------------------------------
ttyS1
------------------------------------------
Note: Optional (커널 파라메터 추가 하는 방법 중 다른 방법, OS 버전마다 구성이 일부 다를 수 있으니 참고)
# vim /boot/grub/grub.conf
------------------------------------------
# splashimage=(hd0,0)/grub/splash.xpm.gz << Comment out (add '#', 주석처리)
Add below two line in top (아래 2 줄 추가, '-'가 2회 필요함에 주의, 가이드에서 1회처럼 기록됨)
serial --unit=0 --speed=115200
terminal --timeout=10 serial console
# cat /boot/grub/grub.conf
------------------------------------------
serial --unit=0 --speed=115200
terminal --timeout=10 serial console

NOTE: UEFI 환경인 경우,
------------------------------------------
# vim /etc/default/grub
add below line's tail - "console=tty0 console=ttyS1,115200"
GRUB_CMDLINE_LINUX="crashkernel=384M rd.lvm.lv=rhel/root rd.lvm.lv=rhel/swap rhgb quiet console=tty0 console=ttyS1,115200"
