Call the XMS driver "Get handle information" function with:
	AH = 0Eh
	DX = handle for which to get info
Return: AX = status
	    0001h success
		BH = block's lock count
		BL = number of free handles left
		DX = block size in KB
	    0000h failure
		BL = error code (80h,81h,A2h) (see #02775)
BUG:	MS Windows 3.10 acts as though unallocated handles are in use
Note:	MS Windows 3.00 has problems with this call
