That's a very old version of ASYN.  I'm not surprised that it has issues.

I don't think the problem is in my files because I can power cycle to device and reboot my soft ioc to reconnect.  The only thing I can imagine is that the generic ASYN driver I'm utilizing (version 4-12 or 4-14) has a bug in it.  Can you guys offer any suggestions?  I'm running EPICS version R3.14.8.2.  I tried running R3.14.11, but there are some incompatibilities noticed, so I'm sticking with R3.14.8.2 for now.
