Hello, EPICS mates.

I implemented the Model 3 of EPICS motor driver support for some motor controller,

but the VAL and RBV of the motor record are zero after IOC reboot.

I think the motor record doesn't restore the values of motor pulse and encoder count from the motor controller after IOC reboot.

What member functions of asynMotorController and asynMotorAxis classes should I implement?

Best regards.
