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.

In the file /etc/securetty add a new line with the name of the serial tty for COM2:

ttyS1

The following example shows a sample file with the new line.

vc/1
                                 vc/2
                                 vc/3

                                 vc/5
                                 vc/6
                                 vc/7
