If serialPort.IsOpen Then
serialPort.Close()
End If
Try
With serialPort
.PortName = "COM1"
.BaudRate = 57600
.Parity = IO.Ports.Parity.None
.DataBits = 8
.StopBits = IO.Ports.StopBits.One
End With
serialPort.Open()
Catch ex As Exception
MsgBox(ex.ToString)
End Try

actually this code i am using for scanner detection through serial port . I checked the setting of scanner in pc its having the same setting whatever i am using in code but through my code i am not able to scan .I have 4 scanner having the same setting my code is working for 3 scanner.Scanner which is not working through my code is working scanner its not having any problem i already check. So can u help me what should be the modification in this code for proper working in all scanner. Otherwise can u help me how to autodetect the scanner without hard coding the baudrate.
