I never noticed this before on my Cobra board , but it may be normal…
If I send data out a UART when the connections of the port are left disconnected I get frame errors on the SerialPort error event. Is this normal? My Domino does not exhibit this behavior.
static SerialPort UART = new SerialPort("COM1", 115200); UART.Open(); byte buffer = Encoding.UTF8.GetBytes("String"); // send the bytes on the serial port UART.Write(buffer, 0, buffer.Length);
