source: fact/tools/FAD/fadfake/fadfake.cpp@ 17841

Last change on this file since 17841 was 9887, checked in by neise, 15 years ago
added 'fadfake' a programm acting as a FAD board. still with very limited funcionality, but nice for testing... added a function OpenServerSocket() to SocketFunctions.cpp
