CIM_POTSModem class
The CIM_POTSModem class represents a device that translates binary data into wave modulations for sound-based transmission by connecting to the Plain Old Telephone System (POTS) network.
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.
