the question says near all: How do I write a (presumably character)
device driver for the AT? Where should I look for docs? The tons of
documentation that I found here when I got the job cover nearly
everything, but not how to write an AIX device driver...
The device in question is a 8-bit PC card, which is read-only at an
I/O address port. Yes, I sort of found the relevant machine language/
machine architecture reference chapters in the documentation.
