Checksum and CRC Classes

These classes implement general-purpose integrity check routines for computing checksum and 16 & 32 bit CRC values for packets of data.

Features:
•	Checksum and 16 & 32 bit CRC integrity check methods 
•	32 bit CRC is compatible with PKZIP CRC 
•	Calculation on memory blocks and files 
•	Support for optional CRC polynomial 
•	Fast and efficient algorithms 
•	Easy to implement 
•	Straightforward C++ interface 

Serial Port Communication classes

Features:
•	control your serial communication with an object oriented approach; 
•	compatible with MFC CFile serialization; 
•	extended exception handling; 
•	build-in user-interface for serial communication settings; 
•	configuration settings are streamable to disk;
