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

[Kim J. Schmock]

Thx
That solved the issue.

I was just wondering why handle_signal() are called rapidly. Shouldn't
it preempt the application until a character arrives at the COM1?
It seems like it is polling, or maybe reacting on an event related to
the handle for the COM1 port.
