I'm familiar with using EXCP to do channel I/O. However the IOB structure
and EXCP seem to be geared towards devices that do not present 
asynchronous attention interrupts. In VM environments, it is very easy
to setup interrupt handlers with HNDIO.

How does one write code in MVS to handle devices such as 3270 terminals
that present asynchronous interrupts?

Thanks for any help,
