+ * also based on the work done by Rick Bronson
+ *
+ * History:
+ * - 0.30 - initial version
+ * - 0.31 - moved ioP96ReadScannerImageData and ioP98ReadScannerImageData
+ * into this file
+ * - added SPP-read functions
+ * - 0.32 - changes in function ioControlLampOnOff()
+ * - made IOReadingImage a local function -> ioP98ReadingImage()
+ * - rewritten function ioP96ReadScannerImageData()
+ * - moved function IOSetStartStopRegister to p9636.c
+ * - 0.33 - added debug messages to IOPutOnAllRegisters
+ * - fixed a bug in ioP96InitialSetCurrentSpeed
+ * - 0.34 - no changes
+ * - 0.35 - no changes
+ * - 0.36 - removed some warning conditions
+ * - 0.37 - moved functions IOSPPWrite(), IODataToScanner(), IODataToRegister(),
+ * IODataFromRegister() to io.c
+ * - moved the data read functions to io.c
+ * - renamed IOInitialize to IOFuncInitialize
+ * - 0.38 - moved some functions to io.c
+ * - added P12 stuff
+ * - 0.39 - no changes
+ * - 0.40 - no changes
+ * - 0.41 - no changes
+ * - 0.42 - changed include names
+ * - 0.43 - fixed a problem in ioP96InitialSetCurrentSpeed(), for COLOR_BW
+ * at least, used the setting for A3I
