Then now would be a good time to urge you to try the motor *driver*
interface that now supports access to motor controller primitives
through an Asyn interface. Configure an asyn port onto the controller,
and you can connect primitive records (ai, ao, etc) to control points
such as VELOCITY, ACCEL, MOVE_ABS, LOW_LIMIT, etc.

I know that it currently comes bundled with the motor *record*, but you
don't have to actually use the record on top of it all.

Assistance in supporting/porting other controllers than the original
PMAC, XPS, MM4000 (and tentatively OMS58/MAXv) will be gladly provided.
