Int 21/AX=5F44h

LAN Manager Enhanced DOS - LOCAL NetWkstaGetInfo

AX = 5F44h
BX = information level (00h, 01h, or 0Ah)
CX = buffer size
DX = 0000h
ES:DI -> buffer in which to store info (see #01714,#01715,#01716),
including any returned strings

Return:
AX = error code
DX = amount of buffer required, unchanged if supplied buffer large
enough to hold data
