How Do I Use the "Is Port Connected" VISA Serial Property?

Primary Software: LabVIEW Development Systems>>Professional Development System
Primary Software Version: 7.1.1
Primary Software Fixed Version: N/A
Secondary Software: N/A
Hardware: Serial

Problem:
I am trying to use the Is Port Connected VISA Property to detect if I have anything connected to my serial port, but I keep obtaining an error. What am I doing wrong?

Solution:
In order for LabVIEW to detect whether or not there is anything connected to the serial port, the port must be from National Instruments and controlled by the NI-Serial driver. National Instruments sells several serial products, including USB and PCI serial ports. If you try to use this property with your built-in serial port, such as COM1, you will obtain error code -1073807331.
