Subject: Streamdevice/asyn Question

I am writing a soft ioc for a gpib device using streamdevice with asyn.  The device in question can send an unsolicited text message, which I do not know how to handle.  I tried defining a record with SCAN "I/O Intr" but cannot make it work, mainly I think, because there are a number of such messages possible and they are all different.  Basically, I want to capture the message in a record and display it on an edm screen.
The streamdevice manual hints that a record with SCAN "I/O Intr" approach might work.  In the manual there is also a mention of mismatch exception handler.  There aren't enough details for me to know how to implement something that works.

Thanks in advance,
Zen
