+/**\r
This routine determines the operational state of the UNDI. It updates the state flags in the\r
Command Descriptor Block based on information derived from the AdapterInfo instance data.\r
-\r
To ensure the command has completed successfully, CdbPtr->StatCode will contain the result of\r
the command execution.\r
-\r
The CdbPtr->StatFlags will contain a STOPPED, STARTED, or INITIALIZED state once the command\r
has successfully completed.\r
-\r
Keep in mind the AdapterInfo->State is the active state of the adapter (based on software\r
interrogation), and the CdbPtr->StateFlags is the passed back information that is reflected\r
to the caller of the UNDI API.\r
