//  tstfind.C - Test application to search for all 1-Wire devices on 1-Wire 
//              Net.
//
//  Version: 1.03
//
//           1.02 -> 1.03  Removed caps in #includes for Linux capatibility
//                         Removed "ds2480.h", <windows.h> and <conio.h> 
//                           includes because not needed
//                         Added "mlan.h" include to define TRUE/FALSE
//                         Prompt to search again 
//                         Changed to use Aquire/Release 1-Wire Net functions
