X X The port seings determine the mapping between the COM port on the client
system and the redirected COM port on the remote desktop and determines
other seings that aect the redirected COM port. You congure each
redirected COM port individually.
Five port seings policy seings are available, allowing up to ve COM ports
to be mapped from the client to the remote desktop. Select one port seings
policy seing for each COM port that you intend to congure. When you
enable the port seings policy seing, you can congure the following items
that aect the redirected COM port:
n
The Source port number seing species the number of the physical COM
port that is connected to the client system.
n
The Destination virtual port number seing species the number of the
redirected virtual COM port on the remote desktop.
n
The Autoconnect seing automatically connects the COM port to the
redirected COM port at the start of each desktop session.
n
With the IgnoreDSR seing, the redirected COM port device ignores the
Data Set Ready (DSR) signal.
n
The Pause before close port (in milliseconds) seing species the time to
wait (in milliseconds) after a user closes the redirected port and before the
port is actually closed. Certain USB to Serial adapters require this delay to
ensure that transmied data is preserved. This seing is intended for
troubleshooting purposes.
n
The Serial2USBModeChangeEnabled seing resolves issues that apply to
USB to Serial adapters that use the Prolic chipset, including the GlobalSat
BU353 GPS adapter. If you do not enable this seing for Prolic chipset
adapters, connected devices can transmit data but not receive data.
n
The Disable errors in wait mask seing disables the error value in the
COM port mask. This troubleshooting seing is required for certain
applications. For details, see the Microsoft documentation of the
WaitCommEvent function at
hp://msdn.microsoft.com/en-us/library/windows/desktop/aa363479(v=vs.
85).aspx.
n
The HandleBtDisappear seing supports BlueTooth COM port behavior.
This seing is intended for troubleshooting purposes.
n
The UsbToComTroubleShooting seing resolves some issues that apply to
USB to Serial port adapters. This seing is intended for troubleshooting
purposes.
When you enable the port seings policy seing for a particular COM port,
users can connect and disconnect the redirected port, but users cannot
congure properties of the port on the remote desktop. For example, users
cannot set the port to be redirected automatically when they log in to the
desktop, and they cannot ignore the DSR signal. These properties are
controlled by the group policy seing.
N A redirected COM port is connected and active only if the physical
COM port is connected locally to the client system. If you map a COM port
that does not exist on the client, the redirected port appears as inactive and not
available in the tool tray menu on the remote desktop.
When the port seings policy seing is disabled or not congured, the
redirected COM port uses the seings that users congure on the remote
desktop. The Serial COM Redirection for VMware Horizon menu options are
active and available to users.
These seings are in the VMware View Agent  > Serial COM >

priority
X X Gives priority to the seings that are congured on the remote desktop.
When you enable this policy, the serial port redirection seings that a user
congures on the remote desktop take precedence over the group policy
seings. A group policy seing takes eect only if a seing is not congured
on the remote desktop.
