  I trying to send a string to a Quasar relay kit #3108v3 using the code below. The com port is opening ok yet I can trigger a relay? Help its so easy in qbasic a simple print command.

   Imports System
  Imports System.IO.Ports
  Namespace Shauntrapmatic.test
  
      Public Class shauntest
          Public Shared Sub Main()
  
  
              Console.WriteLine("Available Ports on this computer:")
              For Each portname As String In SerialPort.GetPortNames
                  Console.WriteLine("PORT: " & portname)
              Next
              Console.WriteLine()
  
              Dim testport As String = SerialPort.GetPortNames(0)
  
              Using port As New SerialPort(testport)
                  port.BaudRate = 9600
                  port.DataBits = 8
                  port.Parity = Parity.None
                  port.StopBits = StopBits.One
  
                  'Write a string
                  port.Open()
  
                  port.WriteLine("N1")
  
                  port.Close()
  
                  Console.WriteLine("Wrote to the {0} port ", testport)
  
              End Using
  
              Console.WriteLine(Environment.NewLine)
              Console.WriteLine("Main method complete. Press Enter ")
              Console.ReadLine()
          End Sub
  
      End Class
  End Namespace
  

  N1 being the relay's command to turn on relay 1

  What am I doing wrong?????
