populates the structure with the necessary information and registers

the relevant functions with the asyn interface layers. Functions are

registered with the common interface and the octet interface.

This class extends the asynMotorController class, providing device support for the

motor record. It is connected to the lower lever SSH port driver by specifying the

relevant port name when created from the startup script. This class connects to the

driver using the asyn OctetSyncIO interface, thus ensuring the port is locked while the

write/read is taking place.

Method

powerPmacController

Parameters

portName - String name of this port, used by the motor record or

other records to connect to this device.

lowLevelPortName - String name of the low level asyn driver port to

connect to.
