1.0 03-Jan-97 MEA Original
1.1 14-Apr-97 MEA Added SetMidiPort IOCTL
11-Jun-97 MEA Added JoltHWReset IOCTL
17-Jun-97 MEA Added MAX_RETRY_COUNT on IOCTLs
21-Mar-99 waltw Nuked VxDCommunicator, this is NT5 only!
21-Mar-99 waltw Nuked unused IsHandleValid
23-Mar-99 waltw Nuked GetStatusGateData (old Jolt code)
