The device support interface is defined by the record type and not by the device support module. So, in principal, if the record type decides to add a new routine then this will work just fine with devices which follow the rules and specify the proper number of entries for previous revisions of theinterface.
The devGpib for 3.13, Bemjamins version, gpibCore, and devGpib for asyn ALL define a struct gDset that has the first members the same as that used by stansard record types. If a standard record type they will have to be changed. I suspect that other device support may have done the same thing.
