Hello Vnews readers,
This is my first message I have completed without
the help of a computer scientist, so please excuse my
typing.
I have written a DR11W device driver for a interface
to a vector graphics system (Megatek) and I want to
try and transfer this from a SUN 3/160 to another
VME based OS9 system. I have, however, no experience
in writing drivers on a os9 system. I would, therefore,
appreciate any tips on the following or examples of
the following.
A) Books on system programming in the 0S9 System.
B) Any examples of drivers for a character oriented device
like an interface of the above type.
or/and
C) Any pointers to the differences between OS9 and
Unix system programming ( such as how the drivers is
annealed with the current core programs.).
I would like to thank anyone for their help, should they
send any. And please excuse my simplicity if the programming
task is essentially the same. I am asking because we are
considering the change between a SUN and and OS9 system
to gain real-time control over our system ,
Thanks again ,
Malcolmc
