Visual Basic and rs-232 port

[BD]

Hi,
Is it easy to Set up a VB user screen to control data being sent to and recieved from the rs-232 port.
Where should I begin.
thanks.

BD, just use MS Comm control and keep track on the OnComm event for the control ...

Private Sub MSComm_OnComm ()
   Select Case MSComm1.CommEvent
   ' Handle each event or error by placing 
   ' code below each case statement

   ' Errors
      Case comEventBreak   ' A Break was received.
      Case comEventFrame   ' Framing Error
      Case comEventOverrun   ' Data Lost.
      Case comEventRxOver   ' Receive buffer overflow.
      Case comEventRxParity   ' Parity Error.
      Case comEventTxFull   ' Transmit buffer full.
      Case comEventDCB   ' Unexpected error retrieving DCB]

   ' Events
      Case comEvCD   ' Change in the CD line.
      Case comEvCTS   ' Change in the CTS line.
      Case comEvDSR   ' Change in the DSR line.
      Case comEvRing   ' Change in the Ring Indicator.
      Case comEvReceive   ' Received RThreshold # of 
                        ' chars.
      Case comEvSend   ' There are SThreshold number of 
                     ' characters in the transmit
                     ' buffer.
      Case comEvEof   ' An EOF charater was found in 
                     ' the input stream
   End Select
End Sub
