You can configure group policy settings that control the behavior of serial port redirection on your remote desktops. With these policy settings, you can control centrally, from Active Directory, the options that are available in the Serial COM Redirection for VMware Horizon menu on users' 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 on remote desktops and client systems.
These policy settings affect your remote desktops, not the client systems where the physical COM port devices are connected. To configure these settings on your desktops, add the Serial Port Redirection Group Policy Administrative Template (ADMX) file in Active Directory.
