Tourneur:
In first Sirs ,
Many thanks for your help ,
In first sterretje, the data return converted in ASCII format concern uniquely the version of reader format ,the first fonction ,I was test.
After, all the data from the this reader, are in hex fomat.
Thats works ,but I'm trying to reduce the total data received from a Tag ID .
You have ,the mode ,the type of tag ,the CRC ,and the ID ,I would like to remove few of these frame and display them on the IDE monitor ,before display it on a little oled display.
The reader is Nano US, from Netronix ,it's a multiprotocol reader .
I let here the sheets .
And my complete code.

"The easiest way to do that is to avoid use of unreliable Strings, and read all the bytes into a C-string, a zero terminated character array."
I 'm sure you have reason, but it's why I posted my question in this forum ...
Like I explained before ,I kept the little serial communication code from an web thread ,cause I was not arrive to realize a serial communication by myself ,even it's not my first program .
Possibilities ,thats I copied a bad and unadapted code are great possible .
I thinked this RFID system ,could not be very difficult ,and I realized my error ....

I am trying to do the same thing as above with a laser but I'm using a micro and the laser is on Serial1 how do I write that since listen wont work
