   	1.0  	03-Apr-96       MEA     original
			16-Mar-99		waltw	Remove unused DetectMidiDevice declaration
			16-Mar-99		waltw	DEFAULT_GET_DATA_PACKET_DELAY changed from
									1 to 2. 1 worked OK for Win9x, but NT5
									requires a value of 2. See NT RAID# 295373
									(Jolt resets after crash in FlightSym 98)
			29-Mar-99		waltw	Fixed typo by restoring DEFAULT_GET_DATA_PACKET_DELAY
									to 1 and bumping DEFAULT_GET_ID_PACKET_DELAY -> 2
			29-Mar-99		waltw	& dennisle - bump DEFAULT_GET_STATUS_PACKET_DELAY ->2
									This fix may also fix the multi-proc issue.
