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
