//  tstow.C - Test application to test 1-Wire Net functions. No EPROM writes.
//
//  Version: 2.00
//
//  History: 1.00 -> 1.01  Change to use msDelay instead of Sleep. 
//
//           1.01 -> 1.02  Changed to generic OpenCOM/CloseCOM for easier 
//                           use with other platforms.  
//           1.02 -> 1.03  Removed caps in #includes for Linux capatibility
//                         Changed to use Acquire/Release 1-Wire Net functions
//           1.03 -> 2.00  Reorganization of Public Domain Kit 
//
