    Comms Problem

    Hi All

    I am sending 13 characters to my vb6 prog via comms which works most of the time but then for some reason the 13th character becomes the first character and it does this all the time until i reload my vb6 program example:-
    1907122220870 is how it should be but ends up like 0190712222087 help would be very greatful
    Code:
    Private Sub Form_Load()
    Dim textfile As String
     
    Open "C:\users\administrator\dirnames.txt" For Input As #1
    Do While Not EOF(1)
    Input #1, textfile
    FolderCreator.Combo1.AddItem (textfile)
    Loop
    Close #1
    
    ' Show Date on main screen.
    'Label3.Caption = DateValue(Now)
    
    ' Fire Rx Event Every Two Bytes
    MSComm1.RThreshold = 13
    
    ' When Inputting Data, Input 2 Bytes at a time
    MSComm1.InputLen = 13
    
    ' 9600 Baud, No Parity, 8 Data Bits, 1 Stop Bit
    MSComm1.Settings = "9600,N,8,1"
    ' Disable DTR
    MSComm1.DTREnable = False
    
    ' Open COM1
    MSComm1.CommPort = 1
    MSComm1.PortOpen = True
    MSComm1.InBufferCount = 0
    End Sub
    
    
    Private Sub MSComm1_OnComm()
    Dim sData As String ' Holds our incoming data
    Dim lHighByte As Long   ' Holds HighByte value
    Dim lLowByte As Long    ' Holds LowByte value
    Dim lWord As Long       ' Holds the Word result
    
    ' If comEvReceive Event then get data and display
    If MSComm1.CommEvent = comEvReceive Then
    ' Shell ("subst Z: /D")
      'Shell ("net use /Delete Z:")
     
    sData = MSComm1.Input ' Get data (5 bytes)
       ' lHighByte = Asc(Mid$(sData, 1, 1)) ' get 1st byte
       ' lLowByte = Asc(Mid$(sData, 2, 1))  ' Get 2nd byte
        
        ' Combine bytes into a word
       ' lWord = (lHighByte * &H100) Or lLowByte
        
        ' Convert value to a string and display
      '  lblRCTime.Caption = sData

    strBatchPath = "c:\deletevert.bat"
    'the path for the batch file you're using
    strShellCommand = """" & strBatchPath & """"
    'the ridiculous number of quotation marks is necessary
    'when there is a space in one or more of the folder names
    lngRet = wshThisShell.Run(strShellCommand, vbNormalFocus, vbTrue)
    'set 3rd argument above to vbFalse for asynchronous
    'execution of the batch file.
    'label8.caption = ""
    'label9.caption = ""
    If Dir$("e:\" & sData, vbDirectory) = "" Then
    
    Label9.Caption = "Directory does not exist."
