2) these port settings are actual untill they are not changed by VSP AX or application, which opened virtual serial port. If these settings are changed, you get a corresponding message (in that case OnLineControl event). Be carefull, when you are changing this parameter from VSP AX in event body, as you might get into an endless loop.
