How to incorporate serial commands into Labview?

[dzhang]

I have an instrument connected to my computer through a serial (RS-232) cable, and the instrument is controlled via serial commands in a Hyperterminal. Is there any way to use Labview to input serial commands so my instrument can be controlled by a Labview application?

Thank you.

Search Labview examples for "Serial".  There are several examples that show how to write to and read from the serial port.

I would simply use the visa read and writes.  it is easy to do, open a visa sesion using the com port, set your cop port settings (baud rate, start stop and parity bits) write the command set to the port, wait for a reply, do your visa read and then close the resource (all using visa) when done.
