 internal bool acceptData;
internal int myAddress = (int)'h';

private void ErrorReceived( object sender, SerialErrorReceivedEventArgs e )

{

SerialError SerialErrorReceived1 = 0;

SerialErrorReceived1 = e.EventType;

case SerialError.RXParity:

if ( ( SelectedPort.ReadChar() == myAddress ) )

}

}

A DataReceived event can check the state of acceptData before deciding what

to do with new received data. Chapter 10 showed how to assign a method to

the DataReceived event.

 Friend Sub DataReceived _
(ByVal sender As Object, ByVal e As SerialDataReceivedEventArgs)

Dim newReceivedData As String

newReceivedData = selectedPort.ReadExisting

If acceptData Then

' The received address matches our address.

End If
