Can you try this with the current CVS head version of ASYN? This latest version no longer uses EPICS timers -- we found that there were just too many problems trying to cancel I/O operations using a timer callback.

It would be good if you could confirm that this problem has gone away before we release ASYN 4-6.

I tried the CVS version and it looks fine. It works with small timeouts, even with 0 timeout.


I have also tested it with StreamDevice. It works well and connection/reconnection is much faster than before.
