ACK is a non-printable char ... if you run your app in a non screen window, I'd be surprised if you saw them.
Try running your app like this: app | cat -v
should print "^F" for every ACK ... independent of screen

  I have been trying to use screen to run a process in detached mode.  Our process prints ACK characters to the screen, but unfortunately the screen is somehow removing non printable characters.  Other known characters such as bell would come through but not ACK. Is there a setting that I can change to let the screen handle ACK characters?

Thank you
