How can I set the DTR line to high by default when a Windows 7 machine starts up?

Background: My own Windows service sets the condition of the com port lines to indicate its status. One of these is DTR high when in a startup state. However, since my service is set to delayed start, there is a period (2 mins, I think) when the DSR line is low after the machine is powered up, before my service starts and sets the DTR line to high.
