Manager
2) Click on the plus sign (+) next to "Ports."
3) Right click on the "Prolific USB to Serial Port" and click on Properties
4) Click on the "Port Settings" tab. Click the "Advanced" button.
5) Pull down the scrollbar on the bottom, left side and select COM 1, 2, 3 or 4 (NOTE:
Choose one that does not say "in use" next to it). Click "OK."
6) Click "OK" again. Notice that the device will show up as being on the same COM port
that it was before (i.e., COM5), but will show up on the new port if you close the Device
Manager and open it again.
