Hi Peter,

It might be the port name. The name of the Asyn port used for the low level serial comms is PUMP:1, but the name of the port used for the Asyn port driver is TURBO:1. The port name you pass into the database has to be the TURBO:1 name.

But you probably need to pass both names into the driver function (LeyboldTurboPortDriverConfigure), because that would have to connect to the low level port in order to do write and reads from PUMP:1.

Cheers,
Matt

If your driver will do callbacks on the asynFloat64 interface you also need to set that bit in the interruptMask argument to the asynPortDriver constructor.
