This example describes how to send strings to the computer's COM1 serial port.
The Using block allows the application to close the serial port even if it generates an exception. All code that manipulates the serial port should appear within this block, or within a Try...Catch...Finally block with a call to use the Close method.
The WriteLine method sends the data to the serial port.
Sub SendSerialData(ByVal data As String) ' Send strings to a serial port. Using com1 As IO.Ports.SerialPort = My.Computer.Ports.OpenSerialPort("COM1") com1.WriteLine(data) End Using End Sub
