You can configure group policy settings that control the behavior of serial port redirection in your remote sessions. With these policy settings, you can control centrally, from Active Directory, the options that are available in the Serial COM Redirection for Horizon menu in remote desktops.
You do not have to configure these policy settings. Serial port redirection works with the default settings that are configured for redirected COM ports in remote sessions and client systems.
These policy settings affect your remote sessions, not the client systems where the physical COM port devices are connected. To configure these settings for remote desktops and published applications, add the Serial Port Redirection Group Policy Administrative Template (ADMX) file in Active Directory.
