Question

After installation, why some COM port show installation unfinished (at the end of the COM port name has a question mark) ?

Answer

Please follow below steps.

Step 1:Change the PCI slot.
Step 2:Reinstall the driver.
Step 3:Using the eraser wipe the golden finger of the PCI card (Which area connects the PCI slot).
Step 4:Clean the PCI slot. If you still can’t solve the problem, it might be that you renew the driver by online update. The Microsoft database already has SUNIX RS-232 data which is the old or the wrong data, therefore you can’t get the right driver. We recommend you visit our website to download the latest driver and install manually.
