Hi Akbar,

use VISA functions to access the serial port.

How do you want to transfer this "value of 40"? Human-readable text, binary data, any message formatting?

That didn't answer the question.

Let's ask the question a different way.  What is the device on the other side you are sending the data to?  What does it expect the data to look like?

ASCII characters of "4" and "0"?  Should it have a termination character like a line feed or carriage return?

Is it a single byte of value 40?  (That would be an ASCII character of an open parenthesis "("  ).  Multiple bytes?

Read the manual of the "device on the other side" to learn about the communication scheme supported...
