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.

Syntax

class Win32_POTSModemToSerialPort : CIM_ControlledBy
{
  uint16           AccessState;
  Win32_SerialPort REF Antecedent;
  Win32_POTSModem  REF Dependent;
  uint32           NegotiatedDataWidth;
  uint64           NegotiatedSpeed;
  uint32           NumberOfHardResets;
  uint32           NumberOfSoftResets;
};

Members

The Win32_POTSModemToSerialPort class has these types of members:

Properties

Properties

The Win32_POTSModemToSerialPort class has these properties.

AccessState

Data type: uint16
Access type: Read-only

State of controller access to the device. The value Unknown (0) is necessary when a logical device can be commanded by, or accessed through, multiple controllers. This property is inherited from CIM_ControlledBy.

Value	Meaning
1	Unknown
2	Active
3	Inactive

Antecedent

Data type: Win32_SerialPort
Access type: Read-only
Qualifiers: Key

Reference to the Win32_SerialPort instance representing the serial port used by the modem. This property is inherited from CIM_Dependency.

Dependent

Data type: Win32_POTSModem
Access type: Read-only
Qualifiers: Key

Reference to the Win32_POTSModem instance representing the POTS modem using the serial port. This property is inherited from CIM_Dependency.

NegotiatedDataWidth

Data type: uint32
Access type: Read-only

Bus or connection data width in use between devices, when several widths are possible. 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

Bus or connection speed in use between devices (when several are possible). 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). This property is inherited from CIM_DeviceConnection.

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

NumberOfHardResets

Data type: uint32
Access type: Read-only

Number of hard resets issued by the controller. This property is inherited from CIM_ControlledBy.

NumberOfSoftResets

Data type: uint32
Access type: Read-only

Number of soft resets issued by the controller. This property is inherited from CIM_ControlledBy.

Remarks

The Win32_POTSModemToSerialPort class is derived from CIM_ControlledBy.
