USB port TMS

[Vera]

Sorry, of course in the code this was missing:

writePort &H378, HyperEventValue

So the thing would be:

If NewTriggerValue > 0 AND NewTriggerValue < 7 AND TargetPresAbs = 1
Then
        If SetSize = 9 Then
                HyperEventValue = 8
        ElseIf SetSize = 16 Then
                HyperEventValue = 16
        ElseIf SetSize = 25 Then
                HyperEventValue = 24
        End If
End If

writePort &H378, HyperEventValue

Gruss, Vera
