CIM_SerialInterface is a CIM_ControlledBy relationship indicating which devices are accessed through the serial controller and the characteristics of this access.
'The AccessState property indicates whether the controller is actively commanding or accessing the device (value=1) or not (value=2). Also, the value, "Unknown" (0), can be defined. This information is necessary when a logical device can be commanded by, or accessed through, multiple controllers.'
'When several bus and/or connection data widths are possible, the NegotiatedDataWidth property defines the one in use between the devices. Data width is specified in bits. If data width is not negotiated, or if this information is not available/important to device management, the property should be set to 0.'
'When several bus and/or connection speeds are possible, the NegotiatedSpeed property defines the one in use between the devices. Speed is specified in bits per second. If connection or bus speeds are not negotiated, or if this information is not available/important to device management, the property should be set to 0.'
'Number of hard resets issued by the controller. A hard reset returns the device to its initialization or 'boot-up' state. All internal device state information and data are lost.'
'Number of soft resets issued by the controller. A soft reset does not completely clear current device state and/or data. Exact semantics are dependent on the device, and on the protocols and mechanisms used to communicate to it.'
