Virtual seral port (COM port) without NI-VISA

Solved!

Although it is out of my degree of expertise, I tend to agree with these conclusions.

 

Indeed, if I look with the windows "event manager" to the precise date/hour/minute of the installation, there is a report of a problem. A guess is that the plug and play program agrees to install COM3, but crashes at some point later, possibly because of insufficient permissions or signatures. With windows DLL I cannot either change the baud rate and so on.

 

I can get the identity of the chip with windows "device manager" / properties / event, and then I get the parameter USB\VID_XXXX&PID_XXXX.

Then with the database

I have the precise manufacturer brand and chip ID. It does not look like a bad chip. I don’t know the kind of layer that the instrument manufacturer builds on the manufacturer... it’s not my job to dive into that.

 

I am not sure that the plug and play instrument does even try to install a .inf file.

Hello fb35,

 

I have a request. Can you convert the VIs in WinapiSerial.zip to LabVIEW 2018? Thanks in advance.
