Well, I was using a port monitor to debug some of the traffic between my
serial device, and my software, when I noticed the output accidentally.
I am not sure when the behavior started. It used to work fine, I was
using printf to debug things, then I turned off all of those printf
statements, and continued development on the gui side (fox toolkit) of
my application, and then had to go in and modify my low level serial
class and was trying to get my printf debug output again, to no avail.
I have updated cygwin a few times, otherwise I cannot think of anything
specific.
What other details can I provide?
