.NET Framework Serial Ports Asynchronous read
Example
void SetupAsyncRead(SerialPort serialPort)
{
serialPort.DataReceived += (sender, e) => {
byte[] buffer = new byte[4096];
switch (e.EventType)
{
case SerialData.Chars:
var port = (SerialPort)sender;
int bytesToRead = port.BytesToRead;
if (bytesToRead > buffer.Length)
Array.Resize(ref buffer, bytesToRead);
int bytesRead = port.Read(buffer, 0, bytesToRead);
// Process the read buffer here
// ...
break;
case SerialData.Eof:
// Terminate the service here
// ...
break;
}
};
