BaudRate set bug in DF1comm.vb

[Yardape8000]

in beta 319
lines 103 - 105
            If value <> m_BaudRate Then
                If DLL IsNot Nothing Then
                    DLL(MyDLLInstance).CloseComms()

Shouldn't line 104 be:
                If DLL(MyDLLInstance) IsNot Nothing Then

Otherwise it crashes if you change the baud rate value.

Just started looking at the program, looks nice so far.

I noticed the bug in "DF1comm.vb" was not fixed in the new 321 release.

If I do not modify the source code as I mentioned, any compiled programs will crash on launching in set_BaudRate() if it is not set to AUTO.

Thanks

This fix was missed in 3.21

I changed the code to this:

            If value <> m_BaudRate Then
                If Not Me.DesignMode Then
                    '* If a new instance needs to be created, such as a different Com Port
                    CreateDLLInstance()

                    If DLL(MyDLLInstance) IsNot Nothing Then
                        DLL(MyDLLInstance).CloseComms()
                        Try
                            DLL(MyDLLInstance).BaudRate = value
                        Catch ex As Exception
                            '* 0 means AUTO to the data link layer
                            DLL(MyDLLInstance).BaudRate = 0
                        End Try
                    End If
                End If
                m_BaudRate = value
            End If
