实现串口通信 可以收发数据 可以是数字也可以是ASCII(Serial communication)

朋友写的C++645通讯程序，支持645-1997与645-2007,支持自已组帧程序自动添加校验码通讯，可以增加数据标识定义，里面还有部分关于费控通讯代码，挺好，拿来分享(Friend write C++645 communications program to support the 645-1997 and 645-2007, to support their own group the frame program automatically adds the checksum communications, can increase data identifies the definition, there is also a section on the fee control communications code, good for them and share)
