To understand this code, I recommend going back over the pseudocode and trying to follow the data coming in. In the pseudocode I have tried to avoid using any de nite values simply because they can be confusing (especially with the inverted serial input and positive serial output). For this experiment, I have used Microsoft s Visual Basic 6.0 as the application development environment for the host code. I have included the Visual Basic source (3RS Visual Basic.frm) and project (3RS Visual Basic.vbp), and the required les can be found in the code\3RS\vb folder. The BASIC source code is
3RS Visual Basic This Application Polls a Serial Port for an Active PIC microcontroller Connected to it. When Start is Clicked, 0x0FF, followed by 0x0FF is Sent out of the Serial Port. The two Values are checked for a Valid Return (which means the Second 0x0FF is Scrambled by the PIC microcontroller).

If nothing is returned, then the No Connect (Label(0)) is Active, if 0x0FF and no change, then (Label(1)) is Active, if 0x0FF is returned and Mangled, then (Label(2)) is Active. 99.12.30 Myke Predko Dim oldCombo1 As Integer Flag of Old Serial Port Private Sub Combo1_Click() Combo1 Box is Clicked on.
