hi everybody

think about that there is one PC and 8 or 9 barcode scanners that are connected to that PC by com ports..i have to do some modifications on a table in my DB by the actions on com ports...

can i handle this by the way below or do i have to multithread ? if yes (multithread) how many threads do i have to design. for each port or a thread ? or for all ports a thread and a thread for other issues

    Private Sub port1_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles Port.DataReceived
...
   DB modifications
...
    End Sub

    Private Sub port2_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles Port2.DataReceived
...
   DB modifications
...
    End Sub

.......
......

    Private Sub port9_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles Port9.DataReceived
...
   DB modifications

    End Sub
