Bottom line: you can't ask the hardware - it doesn't know and can't tell what the settings are.
As you suggest (and as I suggested in Re: Win32::SerialPort Query Current Values) the only way to figure it out is to "suck it to see". Re-read that reply. It tells you which parameters are important and how they should be set for quickest results.
