Yes, sure. But my job doesn't leave me any time to work
out a good solution except if I take a vacation for it.

I might be able to write a wrapper that just copies the
data structure provided by the new generic code into local
variables, as is done with the current code. Or I might 
be able to complete a version that is limited to a small
number of simultanous commands (ahemm, ONE single command :)
which will be made fully functional a few weeks later 
(famous last words, I know ...)

Well, anyway: I know that you can't accept being kept back
for too long, and I appreciate the changes you have prepared
and hope they'll be intergrated soon. And I know there are
dependencies ... 

I intend to spend a full work on NCR driver issues this 
weekend, but I can't promise that I'll have a preliminary
solution to offer before one or two other week(end)s have 
passed.
