Hi Kevin,

re using generic EPICS records. That is what I have done in the pmac driver by providing :DirectDemand PV (which is linked to a busy record that clears when the motor is done moving).

However, I felt that this was a bit messy, it was a breaking change to the interface and is a one off for our specific controller. A 'dumb' motor record mode would support all intelligent controllers and not require changes to the  software layers above.

Cheers,

giles.

You aren't required to use the motor record to communicate with model 3
asyn motor drivers.  It is possible to use generic EPICS records with
asyn device support to access the various asyn motor parameters, which
would effectively be a 'dumb mode'.
