Loopback not working

I dloaded the loopback vi from ni.com and tried shorting the pin 2 and 3 of RS232 but i don't receive anything back.
I am pretty sure I am using the right COM port.

Thanks tbob.
My COM port was blown up. I tried using the vi on a different station and it worked fine.
Thanks for your help.
