Labview application experts: I would like to create a .VI to handle an application level protocol (let's call it AppProt.VI).  I would like AppProt.VI to use either a serial, TCP/IP, or UDP port.  Is it possible to pass a .VI reference to AppProt.VI so it can use the low level communication device without knowing what it is?  In C++, I would derive SERIAL, TCP/IP, and UDP objects from an abstract base class... say COMMDEV.  AppProt would then be passed a pointer to a COMMDEV object.  What is the equivalent in LabView?Thanks much,Terry
