 I have written a driver that I want loaded at startup (with my INIT)
and be able to call from another application. If I open driver from
within the application, it receives Control calls just fine, but if I
open the driver, close the application, and then start a new appl and
try to send the driver a Control call, I get an address. The driver IS
in memory - the Device Control Entry points to it - but it still doesn't
work. I've written many (working) DAs, but never a non-DA driver. Any
suggestions???
