This has some of the simple serial port functions (as in initing a serial port, set baud rate). But no Ansi C12.18 table, or C12.18 packet tear apart/interpretation/disassembly functions. No packet assembly functions. No Ansi Table defs that would be needed. Doesn't have even the essential meter read function. Nor set time/date function for the meter. Nor Logon functions for the different types of logon. No read interval data functions. Doesn't even have a read of decade 0.

Hi,alex
The code looks elegance, I've never seen such a concise and efficient code.However, there are some details I can not understand,would you kindly give me one or two, sincerely hope to get your answer.
Firstly,the macro of container_of,using a novel way to call the struct,what is the function about and how to understand it.And when I make the code,there is a compile error happened,I try to modify the void to char,it works.
