使用VB6.0编程，通过串口与伺服器通信时，按照MODBUS协议编写的求解LRC校验码的程序-Using VB6.0 programming through the serial port to communicate with the server, in accordance with the MODBUS protocol checksum written procedures for solving the LRC

串口工具完成。加入了校验码功能。有无校验，校验和，异或校验，CRC校验，LRC校验。 2012/9/5 由kylin完成。-Serial tools to complete. Adding a checksum feature. Whether the checksum, checksum and XOR checksum, CRC check, LRC checksum. 2012/9/5 by kylin completed.

自己编写的串口测试程序，可发送、接收16进制码、ASCII码。可加校验码，校验码包括CRC16、CRC8、LRC、CHECKSUM、回车、CONTROL+Z。可循环发送、单次发送。-a serial test tool,programed by myself.

pc与变频器进行串口通讯，采用mscomm进行，并利用LRC校验进行数据传递-pc serial communication with the drive, using mscomm conduct and use LRC checksum data transfer
