An implementation of TCP/IP and associated protocols for amateur packet radio systems. KA9Q is most popular with users of home computers: KA9Q implementations for computers rather than radios run on many varieties of computers (including such unusual models as Ataris and Apple 2's) to allow them to function as standalone Internet-connected workstations. "KA9Q" is the Amateur Radio call sign of the original author, Phil Karns. See also TCP/IP Protocol Suite. WWWebfx Home Page
