That screws up your logic, the value of BytesToRead is unpredictable. It matters to your DataReceived event handler, it will fire one extra time to tell you about Eof. Dates back to the stone age, unfortunately it cannot be changed. It is Ctrl+Z, the default end-of-file character. This at least does not give me strange results in the rest of my application but it is not the perfect solution.Дoes anyone have an idea of what the issue might be? I could bypass the error by ignoring any message containing a byte value of 26. Although i am not sure if it would have any effect. Reading into a string and then converting it into a byte array The buttons are for opening and closing the port. I have a main form with two buttons and a timer. SP_TestCom.Read(DataArray_Temp, 0, SP_TestCom.BytesToRead)ДЄrray.Copy(DataArray_Temp, DataArray, DataArray_Temp.Length) Private Sub SP_TestCom_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SP_TestCom.DataReceivedДim DataArray_Temp(SP_TestCom.BytesToRead + 1) As Byte Public Sub SendData(ByVal Data() As Byte) The first two and last two bytes can never reach a value of 26, it is just the data bytes that can do that. The values are 251,20,(6 data bytes),checksum lo, checksum hi. The data the device is sending consists of 10 bytes. Also i have only one device connected with the test. I have made a short program to only test the serialport. And all data after that is read in the next DataReceived event. Then im not sure what exactly happens but after the byte value of 26 the reading seems to stop. NET 2015 as well.ДЄlmost everything is working well except when one of the devices sends a message with a byte value of 26. The application is written in visual basic.

Reading byte value 26 in SerialPort vb.net I have an vb.net winforms application that reads/writes serial data to several devices connected to a USB-RS485 device. Note that the page(s) also mention the fact that the buffering behavior complicates things. Use the BytesToRead property to determine how much data is left to be read in the buffer. The DataReceived event is not guaranteed to be raised for every byte received. SerialPort.DataReceived Event has an interesting comment which may point you in the right direction: Is the program too slow to get all data or what is the problem? Private Sub com9_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles com.DataReceived If I go even with higher Baud rates (57600) it loses even more lines. It looses around 2-3 lines that were sent over the serial port to the Visual Basic code. I read the serial port in Visual Basic with com.Readline, but it won't read everything.

Serial port in code, Visual Basic 2010 - vb.net I got an Arduino hooked up to the PC and would like to read the serial port of it.
