    Changing the Port settings for Serial-USB.

    Hi,



    Thank you for writing to Microsoft Community Forums.

    If you want to change the port settings, please follow the steps mentioned below:

    1. Open Device manager (right click on start button
      and then on Device manager).
    2. Then expand port (COMS & LPT).
    3. Then right click on Prolific USB-to Serial Comm Port and then on properties.
    4. Go to port settings and click on Advanced.
    5. You will be able to make the changes on this screen.


    Hope this helps.
     
  3. Change serial port defaults, Windows 10

    Thanks for helping. I have done the steps but still unable to connect the serial to this router. Devices and Printers only ever shows generic PnP monitor. PuTTy just shows unable to open the serial port.

    Hyper-V serial port

    Hi

    We have

    Hyper-V Manager version: 10.0.18362.1

    installed on Windows 10. We need to use serial port on victual machine, but could not get correct configuration. We tried some suggestions from internet, such as remote logon the virtual machine and use the serial port on host computer. It does not work neither.
    What is the best way to get serial port on Hyper-V virtual machine?
