There&#x27;s a patch which adds emulation for the popular NE2000 network card: <a href="http:&#x2F;&#x2F;home.arcor.de&#x2F;h-a-l-9000&#x2F;ne2kstuff&#x2F;db_ne2000.html" rel="nofollow">http:&#x2F;&#x2F;home.arcor.de&#x2F;h-a-l-9000&#x2F;ne2kstuff&#x2F;db_ne2000.html</a><p>DOS itself had no networking support. I don&#x27;t think Windows 3.1 had native networking either - you had to install Novell for LAN networking or Trumpet Winsock to use a modem.
