Need help reading data from serial port please

[Guest]

I am trying to use code below to read data form the port. I know it is not
correct but I am not finding what I need in MSDN to help me.

private void serialPort1_DataReceived(object sender,
SerialDataReceivedEventArgs e)
{
string getRelayStates;
getRelayStates = serialPort1.ReadLine();
MessageBox.Show(getRelayStates);

Any ideas?
thanks

CMartin,

Well, you are trying to read an entire line, but when the DataReceived
event is fired, it isn't guaranteed that an entire line is available. Can
you read one character at a time?
