SerialPort CTSChange Delivers a Non-Boolean Value

Description
-----------

Hi

In the following simply event handler I am trying to catch the CTSChange event and to take according action:

Public Sub SerialPort1_CTSChange(CurrentValue As Boolean)

  Print "CurrentValue: "; CurrentValue
 
  If CurrentValue = True Then
    Print "True"
    PictureBox_CTS.Picture = Picture["icons/led_green.png"]
  Else
    Print "False"
    PictureBox_CTS.Picture = Picture["icons/led_gray.png"]
  Endif

End

Although the "Print "CurrentValue: "; CurrentValue" indicates, that the CurrentValue is True, the line "If CurrentValue = True Then" never detects this. Only False is detected.

After I made following change

If CurrentValue = True Then -------> "If CurrentValue Then"

it worked. This told me to try following change

If CurrentValue = True Then -------> "If CurrentValue = 1 Then"

which also works.

This looks to me like a bug in the serialport class. It seems to delivery a Non-Boolean value.

Best regards

Claus
