Low level control of serial port?

[RJM2]

Hi there,

We're using LabVIEW 7.1 and I would like to control some low level aspects of the serial port (I'm having a LOT of difficulty connecting to an ABU93 autoburette). Is there a way to set the DTR, DTS RTS and CTS in LabVIEW 7.1? Is this controllable through VISA?

Thanks for any help,

Russ

Hi,

You should be able to have flow control with "VISA Configure Serial Port.vi"
This is found in Instrument I/O > Serial in functions palette.

The serial lines cannot be adressed using the Configure serial port VI. You need to dig a little deeper, and access the modem property node.
See the attached vi.
