Msvm_SerialController class

Articolo
05/31/2018

Represents the capabilities and management of the serial controller. Serial controllers are logical devices that are always present in a virtual system, and thus are not allocated through a resource pool. One serial controller instance is always present in a virtual computer system. Serial controllers have a fixed number of port instances. This implementation supports two ports per controller.

The following syntax is simplified Managed Object Format (MOF) code, and it includes all of the inherited properties.
