Labview VISA Flush I/O Buffer, how can they be used?

[kas]

I need to flush the i/o serial buffer and the VISA Flush I/O Buffer or
VISA Clear seems to be useful.
How can they be used? I can't find any examples.

I am using Labview 7.1

Do you mean what value to wire to the mask?

If so, here is a description:

VISA Flush I/O Buffer

Flushes the I/O buffer specified by mask.

mask designates the buffer to flush. Combine the buffer masks by bit to flush more than one buffer simultaneously. Use logical OR, also known as OR-ing or adding, to combine the values.

Mask Values	Hex Codes	Description
16	0x10	Flushes and discards contents of the receive buffer.
32	0x20	Flushes and discards contents of the transmit buffer by writing all the buffered data to the device.
64	0x40	Flushes and discards contents of the receive buffer.
128	0x80	No I/O to the device.

although extremely simplistic, here is an example:

This is extremely basic. Have you done the tutorial?
