echo message not coming on terminal with systemd

Question

I have systemd service, say xyzWarmup.service.

Here is the service file

[Unit]
Description=Xyz agent.
After=fooAfter.service
Before=fooBefore1.service
Before=fooBefore2.service

[Service]
# During boot the xyz.sh script reads input from /dev/console.  If the user
# hits <ESC>, it will skip waiting for xyz and abc to startup.
Type=oneshot
StandardInput=tty
StandardOutput=tty
ExecStart=/usr/bin/xyz.sh start

RemainAfterExit=True
ExecStop=/usr/bin/xyz.sh stop

[Install]
WantedBy=multi-user.target

Following is the part of xyz.sh.

                echo
                exit 0
            else
                echo "[ FAILED ]"
                echo "This is failure"  
                               exit 1
            fi
        fi
    done
}

I am unable to see any echo message, after this line in code "if [ "$STATE" = "" ];". When this script runs during boot I just this the following message coming from the script

 Completing initialization (press ESC to skip): 

I don't see "[ OK ]" or "[ FAILED ]" on my screen.

When I was using this script as initscript in Fedora14, I used to see these messages. Once, I have shifted to systemd. I have started seeing this issue.

systemd version is : systemd-201-2.fc18.9.i686 and systemd.default_standard_output=tty

Kindly help.
