Setting Up Desktop and Application Pools in View

Group Policy
Setting Description
Lock
configuration
Locks the serial port redirection user interface and prevents users from changing configuration options
on the remote desktop.
When you enable this setting, users cannot configure the options that are available from the tool tray
menu on their desktops. Users can display the Serial COM Redirection for VMware Horizon menu,
but the options are inactive and cannot be changed.
When this setting is disabled, users can configure the options in the Serial COM Redirection for
VMware Horizon menu.
When this setting is not configured, local program settings on the remote desktop determine whether
users can configure the COM port redirection settings.
Bandwidth
limit
Sets a limit on the data transfer speed, in kilobytes per second, between the redirected serial port and
client systems.
When you enable this setting, you can set a value in the Bandwidth limit (in kilobytes per second)
box that determines the maximum data transfer speed between the redirected serial port and the
client. A value of 0 disables the bandwidth limit.
When this setting is disabled, no bandwidth limit is set.
When this setting is not configured, local program settings on the remote desktop determine whether a
bandwidth limit is set.
This setting is available as a Computer Configuration policy only.
Configure USB to Serial Adapters
You can configure USB to Serial adapters that use a Prolific chipset to be redirected to remote desktops by
the serial port redirection feature.
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.
