Can I unload and reload my serial driver without rebooting my system

Hello,
I am writing a serial port WDM driver and am in the process of
debugging the same. I have installed this device as another COM port in
the system (a W2K machine). But I find it frustating when I have to
restart my debugging machine every time I make small code changes and want
to test it. Is there a way to unload my serial driver and reload it
without restarting my computer.
Regards,
Ganesh
