Ethernet to serial adapter. All rights reserved Last reviewed February 10, Drivers and COM port issues would not relate to specific to system models. They relate to operating system versions, because the operating system would require certain drivers and the operating system assigns COM ports which the user can change through Device Manager.
There isn't a COM number for the entire system. The COM number is assigned to the USB serial port adapter itself whenever it's connected, and again that's all handled by Windows, not the system.
If there was a known issue with your device when trying to use it with certain versions of Windows, that might be understandable, but this wouldn't be a situation where this USB device doesn't work with Dell laptops but works with some other vendor's laptops.
But since you mention this works with other devices, what are these other devices that work properly with this adapter, and what version s of Windows are they running? I have attached the screenshot of the my "Device Manager". My Dell laptop is Windows The PLC is being connected properly with my desktop computer which is also Windows The vendor previously gave me a driver they told that it was mandatory to install for connecting to ANY kind of computers while buying the PLCs which I had installed but found no result.
The vendor also suggested me to try to connect the USB of the PLC to a "9 pin serial port" and then connect that "9-pin serial port" to my Dell laptop. But I think that I will not be succeeded because I am not even able to see the ports in the Device Manager whether it a USB port or a "9-pin serial port". If you have a desktop computer running Windows 10 where the adapter works fine and you can see it under the Ports section of Device Manager, then unfortunately at this point I'm not sure what to tell you.
Anything else I'd want to check would require having access to both systems and time spent troubleshooting rather than just making suggestions in forum posts. Thank you for your kind reply. I would highly appreciate if you would take remote access over the two computers and kindly have a look.
