    You should be able to use the microsoft comm control component. In vb, under projects -> components, choose the comm control.

    this is the program i have written.i wanted see the result by shorting 2 and 3 pins of comm port1.why iam always getting outbuffercount as 0.and mscomm1.input as ""

    Private Sub transmit_KeyPress(KeyAscii As Integer)
    Dim Buffer As Variant

    ' Set and open port
    MSComm1.CommPort = 1
    MSComm1.PortOpen = True

    Buffer = Chr$(KeyAscii)

    MSComm1.Output = Buffer
    MSComm1.InputLen = 0
    Text1.Text = MSComm1.Input
    Text2.Text = MSComm1.OutBufferCount
    MSComm1.PortOpen = False

    End Sub

    please tell the modifications inthis program so that i can check transmit and receiving of data.
