Thread.Sleep(-1); will sleep forever, so your write never gets called. just remove it.
port.Write(teststring, 1, testing.Length); - why start with 1 here? you start with 0.
public static void Main()
{
initComs(); //opens com port and awaits data
Thread.Sleep(500);//added this in case the com port wasn't ready fast enough
//importData(); //imports data from SD card--for later
string teststring= "Powerisoff";
byte[] data = System.Text.Encoding.UTF8.GetBytes(teststring);
port.Write(data, 0, data.Length);
Thread.Sleep(-1);
}
static void initComs()
{
port = new SerialPort("COM1", 19200, Parity.None, 8, StopBits.One);
port.DataReceived += new SerialDataReceivedEventHandler(RecievedData);
port.Open();
}
