Win32_POTSModemToSerialPort class

The Win32_POTSModemToSerialPort association WMI class relates a modem to the serial port the modem uses.

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

Properties

The Win32_POTSModemToSerialPort 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: Win32_SerialPort
Access type: Read-only
Qualifiers: key, Override ("Antecedent"), MappingStrings ("WMI|Win32_SerialPort")

A Win32_SerialPort that represents the serial port used by the modem.

Dependent
Data type: Win32_POTSModem
Access type: Read-only
Qualifiers: key, Override ("Dependent"), MappingStrings ("WMI|Win32_POTSModem")

A Win32_POTSModem that represents the POTS modem using the serial port.

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.

Remarks

The Win32_POTSModemToSerialPort class is derived from CIM_ControlledBy.
