//  tstfind.C - Test application to search for all 1-Wire devices on 1-Wire
//              Net.
//
//  Version: 2.00
//
//           1.02 -> 1.03  Removed caps in #includes for Linux capatibility
//                         Removed "ds2480.h", <windows.h> and <conio.h>
//                           includes because not needed
//                         Added "ownet.h" include to define TRUE/FALSE
//                         Prompt to search again
//                         Changed to use Acquire/Release 1-Wire Net functions
//           1.03 -> 2.00  Changed 'MLan' to 'ow'. Added support for
//                         multiple ports.  Don't stop loop at end of each
//                         search round.
