I'm currently working on my senior project; basically, I need to take over the OpenDevice() call and substitute my own device for the serial.device. However, I still want to be able to use the original OpenDevice() call to do the actual opening (I merely need to substitute one device for another). Is it legal to use the address I get back from SetFunction() to call the original OpenDevice() function? Any info would be greatly appreciated!! -Steve.

Why not put your new device in DEVS: called serial.device and rename the
existing one to amiga-serial.device. Then an open device of serial.device
will get yours and an opendevice() of amiga-serial.device will get the amiga's.

I believe it is, although I personally haven't tried it.
