Go To Local GTL RenMode

[opticyclic]

I am programming using VB.NET 2005.

I am trying to set my instrument (HP8753C VNA) to local.

The manual says there is a GTL command but obviously I can't just send it with a MessageBasedSession.

This is the info in the help for the NationalInstruments.VisaNS that I found for REN and GTL, but I can't work out how to apply it.

Despite the help I managed to work it out

        Dim GPIB As NationalInstruments.VisaNS.GpibSession
        GPIB = CType(ResourceManager.GetLocalManager().Open("GPIB0::16::INSTR"), NationalInstruments.VisaNS.GpibSession)
        GPIB.ControlRen(RenMode.AddressAndGtl)
        GPIB.Dispose()
        GPIB = Nothing

The VISA help for .NET needs extra links to other relevant parts of the help.
