There's a simple solution to that problem. Just start running statserial (or whatever program you like) _before_ plugging anything into the serial port. Then you can set RTS and DTR to their proper values right away and afterwards watch what happens. (However, I suspect you won't be able to use the serial port in another program while statserial is running. Maybe that's okay for what you want to do.)
