Double check the port settings when running the driver to make sure they are the same as what you are using in VISA Test Panel.  Also make sure the port is closed properly before attempting to open it again.

Hi Ahmed,

error -1073807246 (or hex BFFF0072) says: "resource is valid, but you cannot access it right now"…

Most probably you are trying to access the device using some other software which blocks the COM port! A COM port is a shared resource, which can be accessed only by one instance!

Btw. it would help when you show the full error code in all of your images: in image 06 it is (partly) hidden…

Hi Ahmed,

in image 08 you still have the "shared resource not available" error - as explained above.

In image 10 you get a "framing" error, which most often occurs when setting a wrong baud rate or when "jumping" into the middle of a serial transmission. Usually all you need is to either apply the correct settings or to delete the error and try to read again…
