Por qué no me agrega nada al .TXT

[IAO]

Holaaaaaa:

Algúno de los cerebros en VB, podría decirme por qué el programa no me agrega nada en el txt?.
Me aparece como si se grabó algo, pero cuando abro el txt no hay nada.

Gracias anticipadas por responder.

Holaaaaaaa:

Asi lo pude hacer funcionar, más  o menos bastante aceptable.

Código: [Seleccionar]

Option Explicit

'''Boton Closecomm1
Private Sub Closecomm1_Click()
'''Close the port if it is open
    If MSComm1.PortOpen = True Then
    MSComm1.PortOpen = False
    End If

End Sub

Private Sub Form_Load()
Dim FileName As String
FileName = App.Path & "\RS232.txt" 
Open FileName For Output As #1

'''Chose correct settings for your device
Dim CommPort As String, Settings As String

MSComm1.CommPort = 1                'puerto com1
MSComm1.Settings = "9600,n,8,1"     'configuracion del puerto serie
MSComm1.PortOpen = True             'se abre el puerto para que funcione
MSComm1.RThreshold = 1              'cada byte recibido, dispara el evento OnComm

End Sub
 
 Private Sub MSComm1_OnComm()
 Dim Inbuff As String     

If MSComm1.CommEvent = comEvReceive Then           'si el puerto comienza a recibir .....
  Inbuff = MSComm1.Input                           'en esta variable se almacena lo que entra por el puerto serie
     Print #1, Inbuff
End If

 End Sub
 
Private Sub Form_Terminate()    '''Cuando se finaliza el Formulario
    If MSComm1.PortOpen = True Then
    MSComm1.PortOpen = False
    End If
   
    Close #1
End Sub

Allí se los dejo, para que sufran menos al momento de querer hacer algo parecido.
