getty
You can run a service called getty to enable login on the serial interface.
To enable getty, append the following line to the list of gettys in the
/etc/inittab file:
7:12345:respawn:/sbin/agetty 9600 ttyS0
Note – It does not matter where you append this line in the list.
Note – Make certain that the first number is unique within the inittab file.
The list of gettys currently looks like the following:
# Run gettys in standard runlevels
1:2345:respawn:/sbin/mingetty tty1
2:2345:respawn:/sbin/mingetty tty2
3:2345:respawn:/sbin/mingetty tty3
4:2345:respawn:/sbin/mingetty tty4
5:2345:respawn:/sbin/mingetty tty5
6:2345:respawn:/sbin/mingetty tty6
securetty
To add the serial-console device /dev/ttyS0 to the file /etc/securetty,
run the following command:
# echo ttyS0 >> /etc/securetty
