Newer versions of Fedora Linux no longer use the /etc/inittab file for configuing getty. A new method is now used called upstart. This requires a file be created in /etc/event.d with the name of the tty device.
Here is a basic example of the contents of /etc/event.d/ttyb01 running agetty:
# ttyb01 - getty
# This service maintains a getty on ttyb01 from the point the system is
# started until it is shut down again.
start on stopped rc2
start on stopped rc3
start on stopped rc4
stop on runlevel 0
stop on runlevel 1
stop on runlevel 6
To start getty on the port, run the following from the root prompt:# start ttyb01
To stop getty:
# stop ttyb01
