- 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?
