You can configure USB to Serial adapters that use a Prolific chipset to be redirected to remote desktops by the serial port redirection feature.
About this task
To ensure that data is transmitted properly on Prolific chipset adapters, you can enable a serial port redirection group policy setting in Active Directory or on an individual desktop virtual machine.
If you do not configure the group policy setting to resolve issues for Prolific chipset adapters, connected devices can transmit data but not receive data.
You do not have to configure a policy setting or registry key on client systems.
Verify that the Serial Port Redirection setup option is installed on your desktops. The group policy settings have no effect if serial port redirection is not installed. See Install Horizon Agent on a Virtual Machine.
Verify that the Serial Port Redirection ADM file is added in Active Directory or on the desktop virtual machine. See Add the Serial Port Redirection ADM Template in Active Directory.
Familiarize yourself with the Serial2USBModeChangeEnabled item in the PortSettings group policy setting. See Serial Port Redirection Group Policy Settings.
- In Active Directory or on the virtual machine, open the Group Policy Object Editor.
- Navigate to the folder.
- Select the PortSettings folder.
- Select and enable a PortSettings group policy setting.
- Specify the source and destination COM port numbers to map the COM port.
- Select the Serial2USBModeChangeEnabled check box.
- Configure other items in the PortSettings policy setting as needed.
- Click OK and close the Group Policy Object Editor.
USB to Serial adapters can be redirected to remote desktops, and can receive data successfully, when users start their next desktop sessions.
