As usual with streams in Gambas, that event is called Read [1].
I don't have anything to connect to a serial port (if I even have
one), but it would look like this:

  ' Assuming you have a SerialPort1 object
  Public Sub SerialPort1_Read()
    Dim iByte As Byte

    iByte = Read #Last, 1
    ' Do something with your byte...
  End

Gambas has builtins for bit manipulation [2].
