Configuring Remote Desktop Features

Table Of Contents
After you install Horizon Agent and set up the serial port redirection feature, the feature can work on your
remote desktops without further configuration. 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. If so, the COM port is mapped to avoid conflicts. For example, if COM1 and COM2
already exist on the remote desktop, COM1 on the client is mapped to COM3 by default. You do not have
to configure the COM ports or install device drivers on the remote desktops.
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. A user can also set a COM port device to connect
automatically whenever the user logs in to the remote desktop. See User Operation of Serial Port
Redirection.
You can configure group policy settings to change the default configuration. For example, you can lock
the settings so that users cannot change the COM port mappings or properties. You can also set a policy
to disable or enable the feature altogether. With an ADMX template file, you can install serial port
redirection group policy settings in Active Directory or on individual desktops. See Configuring Serial Port
Redirection Group Policy Settings.
When a redirected COM port is opened and in use on a remote desktop, you cannot access the port on
the local computer. Conversely, when a COM port is in use on the local computer, you cannot access the
port on the remote desktop.
System Requirements for Serial Port Redirection
With this feature, end users can redirect locally connected, serial (COM) ports, such as built-in RS232
ports or USB to Serial adapters, to their remote desktops. To support serial port redirection, your Horizon
deployment must meet certain software and hardware requirements.
Remote desktops
The remote desktops must have View Agent 6.1.1 or later, or Horizon Agent
7.0 or later, installed with the Serial Port Redirection setup option, on the
parent or template virtual machines. This setup option is deselected by
default.
The following guest operating systems are supported on single-session
virtual machines:
n
32-bit or 64-bit Windows 7
