// - Written 1996-1998 by Christoph Schmelnik   -
// ----------------------------------------------

// Changes
// ===========
// Version 1.2 :
// -CMapDrive supports now up to 34 Host Adapters, because now it could access the drives under
// NT with the DeviceControl Interface
// The required information for this is coded as:
// Drives accessed over the new Interface have a HostAdapterNumber above or equal to the
// NumberOfHostAdapters (global Information).
// The ID consists of the good old drive number, like in DOS.
// The LUN is not used for the configuration, but it is used to hold the open handle to the device
// The Burstmodus couldn't be used with the new access mode, so the default setting for those
// drives is the Normal-mode. (For those drives is no difference between Burst- and Normal-mode)
// -LoadASPI checks now the Windows Version and hold this result global in the DLL
// -The Constructor of CSCSCD opens the handles to the new devices
// -The destructor closes those handles
// Interface changes are not required but some values must be handled differnt to avoid
// misconfiguring, e.g. it is not allowed to configure the new drives ID, LUN, and HostAdapterNumber
// -A bug in CWaveSave regarding conversion to mixed mono has been fixed.
//
// Version 1.33 : 18.01.1998
// Changes:
// Added speed selection support for all current Plextor drives
//
// Version 1.40 : 24.02.1998
// Changes:
// Set correct direction flags, to work with NT device IO interface and ATAPI drives
// Changed main CD detection to TestUnitReady
// Removed CD detection from Audio Status Info
// Added hopefully correct read command for Matsushita/Panasonic drives 
// Added Parameters to CDAC class to allow the disabling of the audio test and to spin up the drive for a specified time
// in seconds to avoid spin up problems on some drives. Both parameters have default values so it behaves like the old version
// without the additional parameters
// Added Parameter to the constructor of CWaveSave to disable writing any Headers. Also this parameter has a default to work like
// before.
// Added virtual function in CDAC to report buffer underruns in Burst Copy Mode
// For the last feature an immediate parameter in WaitCDDA is added
// GetLastSense function added to return the sense information for the last read audio command
// Configuration in CMapDrive extended by new features
// Fixed GetRedBook operator in CCDAdress
// Added function to CD Class to read Media Cataloge Number
//
// Version 1.41 : 28.04.1998
// Changes:
// New GetInfoEx() function in CMapDrive, to allow a better result checking.
//
// Version 1.42 : 02.08.1998
// Changes:
// Added GetLastReadableAddress function to get the last readable Sektor of a session.
// Added a flag in the drive properties for the function.
// Added this function to the CDAC object.
//
// Version 1.43 : 23.12.1998
// Changes:
// Added Wave and DAC classes are now available in a MT version, the old versions will not longer be updated.
// 
// Version 1.44 : 10.03.1999
// Changes:
// Added Support for current Plextor CDROM drives and CD-Writers.
// Added Support for Jukeboxes
// Changed Handling of the Ringbuffer
//
// Version 1.45 : 15.08.1999
// Changes:
// Added Enhanced error detection for Plextor drives.
// Several Bugfixes (initialising under NT and Ringbuffer specific)
//
// Version 1.45-Build 11 : 11.11.1999
// Changes:
// Added a check for the MaxSektor parameter in CBaseWaveMT to avoid Program failures even if the applications provides an invalid value.
// Changed source to comile with Borland compiler
// Added MMC-2 Type which will be default for Sony CD-Writers 140 and 928
// Skip Virtual CD devices in Bus scan
// Fixed Array out of bound bug in drive detection.
