4.1 --> 4.3 BSD Device Driver Conversion

[Kenneth Kutz]

I will be attempting to port a 4.1 BSD device driver to run on our
4.3 BSD system.  The system is a VAX 11/785.  The device is a National
Instruments GPIB 11-2 (General Purpose Interface Board) for the
Unibus.  The interface supports DMA transfers and is IEEE-488 compliant.

If anyone has undergone a similar undertaking, I would appreciate any
pointers.  From looking at the errors from my compile listing, it
appears the return values are passed differently in the 4.1 implementation.

Thanks,
