wish of those help Serial communication allows to break data flow into messages by using timeout. But following KISS TNC there no such functionality is presented in this protocol.

Reading binary data with PySerial from serial port
Date : March 29 2020, 07:55 AM
wish of those help It seems that PySerial (or a library that Pyserial depends on) is translating a single "0x0a" (\n) character into two characters "0x0d 0x0a"(\r\n). Both communication end-points are running on Linux, so I am not sure why someone would like to even translate those line endings at all... Here strace indicates that sender sends only \n to ttyS0: write(1, "M\n", 2) = 2
write(1, "\n", 1) = 1
write(1, "M\n", 2) = 2
write(1, "\n", 1) = 1

Any of those help I try to write some binary data to the Serial Interface with C#: , you can try this : using System.IO.Ports;
public void TestSerialPort()
{
SerialPort serialPort = new SerialPort("COM1", 115200, Parity.None, 8, StopBits.One);
serialPort.Open();
byte[] data = new byte[] { 1, 2, 3, 4, 5 };
serialPort.Write(data, 0, data.Length);
serialPort.Close();
}

How to read Binary Data from Serial Port without any Encoding?
Tag : chash , By : Frank Bradley

I hope this helps . Your code is constructing a System.String instance from a byte array, which will attempt to form a valid text value from the bytes using the default encoding, whatever that happens to be on your system. Either you need to change your SerialDataEventArgs class to use byte[] instead of string or convert the byte array to a string of hex digits using BitConverter.ToString(data) or similar. Something like: //class SerialDataEventArgs
public class SerialDataEventArgs : EventArgs
{
public string Data;
public SerialDataEventArgs(byte dataInByteArray)
{
Data = BitConverter.ToString(dataInByteArray).Replace("-", " ");
}
}

C# send data over serial port in binary mode

like below fixes the issue Can someone please let me know what is the difference between "Binary mode" and "Not-binary mode"? If you select this option, received characters are sent without any modifications.
Otherwise, new-line codes are converted and control characters (except TAB, LF and
CR) are stripped out.
