Hi

You do this by using VISA got to Functions-> Instrument I/O-> serial, also see examples give with LabVIEW for the same

LabVIEW Examples-> hardware i/o -> serial

Hope this helps

You can use a string control  and a local variable to write to it.

Here is an example that uses the event structure and the property node to find out what you typed in. And send out only the new characters no matter where you type it in the control. But beware, I don't say this is fool proof

The string recieved is added at the end of the string.

VI is LV7.1

ups,  that wasn't what you where looking for . Select HELP - Find examples and search for simple serial read write . You will need a null modem cable to read the same characters.
