I'm writing a device driver using serial communications (i e COM 1 - 4).

As far as I can see the MSDOS systems initializes the interrupt
vectors for COM 1 - 4 __AFTER__ the drivers has been loaded.

This destroys the vectors I've just installed during the INIT-pahase in
the just loaded device driver.

Is this correct? Can I circumvent this?
