Subject: Devices Which Send Unsolicited Messages

This is a follow up question to a comment that Dirk Zimoch made in another

thread.

We use Asyn for almost all of our device drivers, however up till now none

of the devices we have used send unsolicited messages.   We live in fear

of the day when we encounter such a device because we don't know how to

handle these messages in Asyn.  In fact, Dirk commented that this is not

even supported in Asyn.  If this is true, what is the canonical method in

EPICS of writing a device driver which copes with such a device?
