Client hardware access

Use this policy to specify maximum number of serial ports supported by the client platform.

Also, use this policy to enable and restrict the remote application or desktop's access to the client's serial, USB, and parallel ports. This allows the server to use locally attached hardware.


Troubleshooting:
Remote PDA synchronization uses "virtual COM ports". These are serial port connections that are routed through USB connections. It is necessary to enable serial port access to use PDA synchronization for this reason.

Supported on: ADMX Migrator encountered a policy that does not have a supportedOn value.
