X X Provides centralized management of scanner autoselection.
You select scanner autoselection options separately for TWAIN and WIA
scanners. You can choose from the following autoselection options:
n
None. Do not select scanners automatically.
n
Autoselect Automatically select the locally connected scanner.
n
Last used Automatically select the last-used scanner.
n
 Select the scanner name that you type in the  scanner
text box.
When you enable this seing as a Computer Conguration policy, the seing
determines the scanner autoselection mode for all users of the aected
computers. Users cannot change the Default Scanner option in the VMware
Horizon Scanner Redirection Preferences dialog box.
When you enable this seing as a User Conguration policy, the seing
determines the scanner autoselection mode for all aected users. However,
users can change the Default Scanner option in the VMware Horizon Scanner
Redirection Preferences dialog box.
When you enable this seing in both Computer Conguration and User
Conguration, the scanner autoselection mode in Computer Conguration
overrides the corresponding policy seing in User Conguration for all users of
the aected computers.
When you disable this seing or do not congure it in either policy
conguration, the scanner autoselection mode is determined by the
corresponding policy seing (either User Conguration or Computer
Conguration) or by user selection in the VMware Horizon Scanner Redirection
Preferences dialog box.
Configuring Serial Port Redirection
With serial port redirection, users can redirect locally connected, serial (COM) ports such as built-in RS232
ports or USB to Serial adapters. Devices such as printers, bar code readers, and other serial devices can be
connected to these ports and used in the remote desktops.
Serial port redirection is available in Horizon 6 version 6.1.1 and later releases with Horizon Client for
Windows 3.4 and later releases.
After you install Horizon Agent and set up the serial port redirection feature, the feature can work on your
remote desktops without further conguration. 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 conicts. 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
congure 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,” on
page 39.
You can congure group policy seings to change the default conguration. For example, you can lock the
seings 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 le, you can install serial port redirection
group policy seings in Active Directory or on individual desktops. See “Conguring Serial Port
Redirection Group Policy Seings,” on page 41.
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.
