| Name | Data Type | Default Value | Qualifiers |
| Name | Data Type | Value |
| MaxBaudRate | uint32 | |
| Description | string | Maximum baud rate in Bits per Second that is supported by the SerialController. |
| MappingStrings | string | MIF.DMTF|Serial Ports|004.6 |
| PUnit | string | bit / second |
| Units | string | Bits per Second |
| Security | uint16 | |
| Description | string | An enumeration that indicates the operational security for the Controller. For example, information that the external interface of the Device is locked out (value=4) or "Boot Bypass" (value=6) can be described using this property. |
| MappingStrings | string | MIF.DMTF|Serial Ports|004.9 |
| ValueMap | string | 1, 2, 3, 4, 5, 6 |
| Values | string | Other, Unknown, None, External Interface Locked Out, External Interface Enabled, Boot Bypass |
| Capabilities | uint16[] | |
| ArrayType | string | Indexed |
| Description | string | The Capabilities property defines chip level compatibility for the SerialController. Therefore, this property describes the buffering and other capabilities of the SerialController that might be inherent in the chip hardware. The property is an enumerated integer. |
| MappingStrings | string | MIF.DMTF|Serial Ports|004.7 |
| ModelCorrespondence | string | CIM_SerialController.CapabilityDescriptions |
| ValueMap | string | 1, 2, 3, 4, 5, 6, 160, 161 |
| Values | string | Other, Unknown, XT/AT Compatible, 16450 Compatible, 16550 Compatible, 16550A Compatible, 8251 Compatible, 8251FIFO Compatible |
| CapabilityDescriptions | string[] | |
| ArrayType | string | Indexed |
| Description | string | An array of free-form strings that provides more detailed explanations for any of the SerialController features that are indicated in the Capabilities array. Note, each entry of this array is related to the entry in the Capabilities array that is located at the same index. |
