NOTE: If the boot loader or operating system provides serial redirection such as GRUB or Linux, then the BIOS
Redirection After Boot setting must be disabled. This is to avoid potential race condition of multiple components
accessing the serial port.
Enabling login to the virtual console after boot
In the file /etc/inittab, add a new line to configure agetty on the COM2 serial port:
co:2345:respawn:/sbin/agetty -h -L 57600 ttyS1 ansi
The following example shows a sample file with the new line.
#inittab This file describes how the INIT process should set up
#the system in a certain run-level.

#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)
