System Requirements for Serial Port Redirection.Conversely, when a COM port is in use on the local computer, you cannot access the port on the remote desktop or published application. When a redirected COM port is opened and in use on a remote desktop or published application, you cannot access the port on the local computer. See Configuring Serial Port Redirection Group Policy Settings. With an ADMX template file, you can install serial port redirection group policy settings in Active Directory or on individual machines. You can also set a policy to disable or enable the feature altogether.
For example, you can lock the settings so that users cannot change the COM port mappings or properties.
You can configure group policy settings to change the default configuration. See User Operation of Serial Port Redirection. A user can also set a COM port device to connect automatically whenever the user connects to the remote desktop or published application. To make a redirected COM port active, a user selects the Connect option from the menu on the serial port tool tray icon during a desktop session. You do not have to configure the COM ports or install device drivers on the remote desktops. For example, if COM1 and COM2 already exist on the remote desktop, COM1 on the client is mapped to COM3 by default. If so, the COM port is mapped to avoid conflicts. For example, COM1 on the local client system is redirected as COM1 on the remote desktop, and COM2 is redirected as COM2, unless a COM port already exists on the remote desktop. Devices such as printers, bar code readers, and other serial devices can be connected to these ports and used in the remote desktops and published applications.Īfter you install Horizon Agent and set up the serial port redirection feature, the feature can work on your remote desktops and published applications without further configuration. With serial port redirection, users can redirect locally connected, serial (COM) ports such as built-in RS232 ports or USB to Serial adapters.
