MS-DOS 3.1 fixes a few bugs in MS-DOS 3.0 and adds the removed networking support via ISF layer and remote file and printer API. The IBM PC-DOS version includes support for IBM's Network Adapter card. PC cloner, Compaq, would release the first EMS memory manager, CEMM, with this version of DOS. CEMM would inspire the design of EMM386, QEMM, 386MAX, NETROOM and many other memory managers.
