Orion Star pH Meter Serial Communication

I have a ThermoScientific Orion Star A211 pH meter which I am trying to communicate with using LabVIEW and the simple serial example VI. The manual says the command to send is GETMEAS. When I use Hyperterminal I have no problems sending the command and receiving the response. However in LabVIEW I only get an echo of the command and not the response string. Any ideas?

I did see this thread which seems to be exactly my problem but when I put in GETMEAS\r\n I still don't get any response. I am using LV2016.
