Okay, I've finally learned that OS/2 is not quite the perfect OS for
lab environments. Maybe I long for a bit of the control of DOS days. Anyway,
I have to write my own device driver to access memory mapped controllers on
a digital to analog (No - of course the manufacturer has no intention of
creating DD in the forseeable future).
I need help. I've got the development kits for OS/2 1.2 and 2.0. They include
some minimal examples of device drivers, but no real documentation. Can
someone tell me where to get adequate documentation to write a trivial device
driver (it will be really stupid). Book suggestions? Pay for more software
from IBM?
Second request: Does anyone have an example device driver (in masm) fully
functional they would make available to me. I need examples of DevHlp calls
to get mapping of physical memory. Any help most greatly appreciated.
