+ HP5400/5470 Test util.
+ Currently is only able to read back the scanner version string,
+ but this basically demonstrates ability to communicate with the scanner.
+
+ Massively expanded. Can do calibration scan, upload gamma and calibration
+ tables and stores the results of a scan. - 19/02/2003 Martijn
