Can we format data in message frames?

[Neha Pa]

Hi All,

Can we format the data in the data frames as follows -


|Header | Message Id | Data Lenght | Data | CRC |Fotter|

If yes can anybody guide me how to do it?

What are "data frames" and "message frames"? Are we talking about something in memory, or networking, or files, or something else entirely?

The data is suposed to be transmitted over RS232 using java. on the receving end C language will read this data frame and decode it to get only DATA.
To send it through RS232 it is requirement to form a data packet i.e data frames in the format I have described above.

Can anybody tell me answer to my post as early as possible?

[Ulf Dittmer]

I would imagine that any data could be sent over a serial connection. Does the documentation of whichever library you're using mention anything about limitations in what you can send?

Actually problem is not sending data over serial communication. That I have already done. I want the actual data to be transfered into data packet format like
|Header | Message Id | Data Lenght | Data | CRC |Fotter|.
So how to do this. I could think of using byte[] array. But is it right?
