RS232l synchronous

[aaairon]

Hello,
I must set in LAbVIEW 6.1 a serial synchronous comunication with an external
microcontroller unit.
In serial port there are Tx, Rx, and CTS/RTS Flow Control.

What is the best way to do it?
In ex: VISA or Serial VI?
can VISA and Serial VI both implement a synchronous comunication?

Thanks

Hi aaairon,

VISA is the recommended programming interface simply because it's platform independent, interface independent, and easy to learn and use.

Please refer to KnowledgeBase 0W1EHK0Z: How Do I Change VISA Reads and Writes from Asynchronous to Synchronous? for detailed instructions.
