It's more complicated than that, unfortunately. ATTN is a feature of
SNA controllers. 3270 emulation via TCP/IP emulates a non-SNA terminal
(regular, local 3270). On such machines, ATTN is not defined at all
(if you press ATTN on a 3270 attached to a local non-SNA controller,
you get X-F - function not supported). In SNA controllers, ATTN generates
a special interrupt RU - an SNA frame.
