DELAY

[Paul Lansky]

In a driver we have for some D-A converters (under Ultrix 1.1)
I put a DELAY(bignumber) (about 1/2 second) in at clean-up time to
give the DACs a chance to reset themselves properly.  This has
the effect, however, of suspending all system activity for that
amount of time.  From the looks of the code (in machdep.c) I don't
see why this would happen since there seems to be no relevant spl().
I ain't no wizard so I may be missing something fundamental.
Can someone suggest an alternate approach?
 
Thanks
