asynch routines

Hello,
 
I tried using the async routines and get a command terminated after
calling ct_poll after calling ct_results. The ct_poll after the
ct_execute worked fine. I checked
the open client manuals and found that a do_update routine can be called
to avoid low level routines being called after the ct_results. I setup a
completion
call back routine and it works fine. The command terminated message
comes up after the completion call back routine completes. I know the
asynch
routines are experimental. Is there something I a missing to make them
work?
 
Thanks,
 
Joe
