VISA Configure Serial Port / Serial Instr

[Greg1997]

What's the difference between VISA Configure Serial Port and VISA Configure Serial Port (Serial Instr)?

LabView 7.0 Help gives no comprehensive explanation:

You can use this polymorphic VI to initialize a serial port using the Instr VISA class or Serial Instr VISA class.

Thanks,

Hi Greg1997,

From what I have seen in LabVIEW 7.1, there is only one VISA Configure Serial Port function block.  It does have a polymorphic VISA Resource Name input to accept either an Instr VISA class reference or a Serial Instr VISA class reference.  The Instr class is a more general class than the Serial Instr VISA class (so there are more specific attributes available to the Serial Instr VISA class), but both references can be used with the VISA Configure Serial Port block.  Hope this helps!
