How to disable CR/LF conversion when sending and receiving binary data over Serial Port ?

I have tried CreateFile which works well for sending the binary data out but receiving binary data always ends up with 0xD being inserted before 0xA.
I need the data to be exchanged with no CR/LF translation.
I have tried using SerialPort and changing the Encoding to UTF8, and Unicode, with no luck.
What should I do ?
Thanks

Igor Tandetnik 1,106 Reputation points2022-09-27T00:02:33.61+00:00 CreateFiledoesn't send any data.WriteFiledoes; andReadFilereceives it. Is this how you write to and read from the port? Show some code.ReadFiledoesn't perform this translation. If you see 0xD 0xA sequence, then either that's what your device sends, or else something you do with the data after reading it has the effect of inserting these characters. -
