    Question recursive function

    Question How to convert MaskedTextbox to DateTime?

    Johns' answer is absolutely correct but as an alternative that I think it's simpler: you can also replace this masked text box for a DateTimePicker, and set 'ShowUpDown = True'; 'Format = Custom'; 'CustomFormat = dd/MM/yyyy hh:mm' that you automatically have a datetime type and don't have to...

    virtual serial port triggers

    I'm sorry but what you're saying is not making much sense. The serial port sends data as a sequence of bits usually coding ASCII characters. You do not individually control it's pins.
