let's focus on perl programming.
I was. Specifically, the IEC 60870-5-101 telegram structure.
But I guess you misunderstood me.

eh, well, I thought whatever protocol the program runs over, the basic procedure would be the same, listen the port, receive request, fetch data somewhere, pack etc. Maybe I was wrong. any suggestions if protocol is IEC 101?
I am trying to improve my English skills, if you see a mistake please feel free to reply or /msg me a correction

In general, when looking to try and help someone, it is easier to read actual documentation, than go through an extended question and answer trying to tie down the details.
Questions like: are the numeric values little or big-endian; how are the checksums calculated; are the packets fixed or variable length; if variable, are they length prefixed or post-delimited; etc. All of this is clear from the documentation.
Which brings me to the question: what is it that you are really asking for help with? What is it that you are having trouble doing?
