[ace-users] Trying to adding an ACE_TTY_IO handler to the reactor.

Hi Kim,

It's been a long time since I've deal with this stuff, but that sounds
like the behavior I recall on Windows if you use an I/O handle rather
than an event handle for serial I/O.

Ok.

I would recommend you read the classic books on advanced Windows systems
programming by Jeff Richter, e.g.,

http://www.amazon.com/Advanced-Windows-Jeffrey-Richter/dp/1572315482

that explains how things work.

> So, ACE_TTY_IO is not able to be used as is with the reactor object without polling?

You may need to tweak stuff a bit to get this working, but it should be
doable.

Have you checked out

ACE_ROOT/examples/Reactor/WFMO_Reactor

to see if there are any examples there that help?

take care,
