CIM_SerialInterface class

The CIM_SerialInterface class represents a CIM_ControlledBy relationship that indicates which devices are accessed through the serial controller and the characteristics of the access.

Important  The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.
 

The following syntax is simplified from Managed Object Format (MOF) code and includes all of its inherited properties. Properties are listed in alphabetic order, not MOF order.

Members

The CIM_SerialInterface class has these types of members:

Properties

The CIM_SerialInterface class has these properties.

AccessState
Data type: uint16
Access type: Read-only

Indicates whether the controller is actively commanding or accessing the device. This information is necessary when a logical device can be commanded by, or accessed through, multiple controllers.

This property is inherited from CIM_ControlledBy.

Unknown (0)

Active (1)

Inactive (2)

Antecedent
Data type: CIM_SerialController
Access type: Read-only
Qualifiers: Override ("Antecedent")

A CIM_SerialController that describes the serial controller.

Dependent
Data type: CIM_LogicalDevice
Access type: Read-only
Qualifiers: Override ("Dependent")

A CIM_LogicalDevice that describes the logical device.

FlowControlInfo
Data type: uint16
Access type: Read-only

Indicates the flow control for transmitted data.

Unknown (0)

Not Supported (1)

None (2)

XonXoff (3)

RTS/CTS (4)

Both XonXoff and RTS/CTS (5)

XonXoff and RTS/CTS

NegotiatedDataWidth
Data type: uint32
Access type: Read-only
Qualifiers: Units ("bits")

When several bus or connection-data widths are possible, this 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 or important to device management, the property should be set to 0 (zero).

This property is inherited from CIM_DeviceConnection.

NegotiatedSpeed
Data type: uint64
Access type: Read-only
Qualifiers: Units ("bits per second")

When several bus or connection speeds are possible, this property defines the one being used 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 or important to device management, the property should be set to 0 (zero).

For more information about using uint64 values in scripts, see Scripting in WMI.

This property is inherited from CIM_DeviceConnection.

NumberOfHardResets
Data type: uint32
Access type: Read-only

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.

This property is inherited from CIM_ControlledBy.

NumberOfSoftResets
Data type: uint32
Access type: Read-only

Number of soft resets issued by the controller. A soft reset does not completely clear current device state and data. Exact semantics are dependent on the device and on the protocols and mechanisms used to communicate to it.

This property is inherited from CIM_ControlledBy.

NumberOfStopBits
Data type: uint16
Access type: Read-only
Qualifiers: Units ("bits")

Number of stop bits to transmit.

ParityInfo
Data type: uint16
Access type: Read-only

Information about the parity setting for transmitted data.

Unknown (0)

None (1)

Even (2)

Odd (3)

Remarks

The CIM_SerialInterface class is derived from CIM_ControlledBy.

WMI does not implement this class.

This documentation is derived from the CIM class descriptions published by the DMTF. Microsoft may have made changes to correct minor errors, conform to Microsoft SDK documentation standards, or provide more information.
