the differences between two ways to communicatet with rs232

[JinHaoren]

There are two different ways to communicate with serial port RS232. I will show as following pictures.

1. The Basic Serial Write and Read. VI.

2. use VISA

So what the differences between these two ways?

Can I also use the method 1 to achieve the functions as shown in method 2?

Thanks

The Basic Serial Write and Read VI uses VISA.  And it is meant as an example.  You can write your code to do whatever you want it to do.
