  *		XcvDataW (WINSPOOL.@)
  *
- * Notes:
- *  There doesn't seem to be an A version...
+ * Execute commands in the Printmonitor DLL
+ *
+ * PARAMS
+ *  hXcv            [i] Handle from OpenPrinter (with XcvMonitor or XcvPort)
+ *  pszDataName     [i] Name of the command to execute
+ *  pInputData      [i] Buffer for extra Input Data (needed only for some commands)
+ *  cbInputData     [i] Size in Bytes of Buffer at pInputData
+ *  pOutputData     [o] Buffer to receive additional Data (needed only for some commands)
+ *  cbOutputData    [i] Size in Bytes of Buffer at pOutputData
+ *  pcbOutputNeeded [o] PTR to receive the minimal Size in Bytes of the Buffer at pOutputData
+ *  pdwStatus       [o] PTR to receive the win32 error code from the Printmonitor DLL
+ *
+ * RETURNS
+ *  Success: TRUE
+ *  Failure: FALSE
+ *
+ * NOTES
+ *  Returning "TRUE" does mean, that the Printmonitor DLL was called successful.
+ *  The execution of the command can still fail (check pdwStatus for ERROR_SUCCESS).
+ *
+ *  Minimal List of commands, that a Printmonitor DLL should support:
+ *
+ *| "MonitorUI" : Return the Name of the Userinterface-DLL as WSTR in pOutputData
+ *| "AddPort"   : Add a Port
+ *| "DeletePort": Delete a Port
+ *
+ *  Many Printmonitors support additional commands. Examples for localspl.dll:
+ *  "GetDefaultCommConfig", "SetDefaultCommConfig",
+ *  "GetTransmissionRetryTimeout", "ConfigureLPTPortCommandOK"
+ *
