一个多功能串口监视工具，同一串口可以有不同波特率来收发数据，带有字符转换工具，可以多种方式的异或校验，也可以CRC校验，也可监视PPP数据包，把PPP数据包内容过虑出来！-A multi-serial port monitoring tool, the same can have different baud rate serial port to send and receive data, with a character conversion tools, you can XOR a number of ways of checking, CRC checking can also can monitor the PPP packets the contents of the PPP packet to worry too much about it!
