CCITT的CRC16代码，自己编写的已通过验证，注意和Matlab的CRC函数有所不同。-This scr ipt calculates the 16-bit ITU-T CRC. The generator polynomial is G(x)=1+ X^5+ X^12+ X^16

自己写的CRCIT算法和校验方法，不同于常见的CRC16或CRC32，在VB环境下通过二进制的方式计算得到结果的代码。-Write their own algorithms and verification methods of CRCIT, unlike common CRC16 or CRC32, in the VB environment by way of the calculated results of the binary code.
