    Need help faster way to read byte from serial

    Hi All,
    I am at a beginner level. I want to read all byte from serial until &H29. I have simple code below but it take over 6 seconds.
    Could you help to make it faster? or share better method. ( I try same data with commercial software it less than 1 sec )

        Function GetBytes() As String
            Dim serialbyte(350000) As Byte 'For example set maximum byte is 350000
            Dim count As Integer = 0
            Dim i As Integer = 0
            Dim rcb As Byte
            While rcb <> &H29
                rcb = SerialPort2.ReadByte
                serialbyte(i) = rcb
                i += 1
            End While
            Dim str = "Nothing"
            Return str
        End Function
