Mark,

I made the changes to asynManager but that made no difference.  I tried 
using the asynSetTraceMask but that did not give me any more 
information.  When I tried using asynSetTraceMask with my ioc that was 
working using asyn 4.5, the ports that I set asynTraceMask for would no 
longer connect.

I have attached the outputs from various ioc configurations.

Thanks

Rob
