Issue

If we want to configure to set up the serial port as a remote terminal in RHEL4,RHEL5, allowing logins via the serial console, how should we do?

Resolution

This is achieved by adding the following line to the /etc/inittab file:
```
co:2345:respawn:/sbin/agetty ttyS0 115200 vt100
```

This option should be added to the the section called # Run gettys in standard runlevels:

# 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
co:2345:respawn:/sbin/agetty ttyS0 115200 vt100

After this edit is made, run the following command:
```
# init q
```
