See my Serial devices

There are several reasons why you may not be able to see your serial devices. First of all, you must have NI-VISA correctly installed on your system. NI-VISA attempts to find all serial ports attached to the system. Ports are listed even if a device is not attached. Some ports cannot be detected dynamically (particularly parallel ports). To allow NI-VISA to see these devices, you must statically add them to the configuration. For serial ports on LabVIEW RT systems, you also need NI-Serial for LabVIEW RT installed.
