+//  Version: 1.03
+//  History: 1.00 -> 1.03 modifications by David Smiczek
+//                        Changed to use generic OpenCOM/CloseCOM  
+//                        Pass port name to OpenCOM instead of hard coded
+//                        Changed msDelay to handle long delays 
+//                        Reformatted to look like 'TODO.C' 
+//                        Added #include "ds2480.h" to use constants.
+//                        Added function SetBaudCOM() 
+//                        Added function msGettick()
+//                        Removed delay from WriteCOM(), used tcdrain()
+//                        Added wait for byte available with timeout using
+//                          select() in ReadCOM()
