# Networking FreeDOS - Crynwr

      The Crynwr packet driver collection provides Network connectivity. They
      were written by Russell Nelson of Crynwr Software. These are based on the
      original ftp.com specification, a skeleton is freely available and most
      network card vendors will provide a packet driver. As this is an open
      standard it is the one most used by GNU and shareware programmers. (See
      also WatTCP).
      There are "shims" which allow both ODI and NDIS NIC drivers to be used,
      but which the applications think are packet drivers.
      The Crynwr drivers are OSI Certified Open Source software. Unlike NDIS
      or ODI, the Packet Driver Specification is freely copyable.
