Yes, the user account I'm running this on is an administrator account.
Running cygwin as administrator (with right-click, run as ...) does not change
the behavior.
I must add that I am able to successfully change the baud rate, but not able to
change most of the other flags. Changing icrnl does not render an error, but
still nothing changed (see below).
(this is on a Windows 7 VM, other HW is the same)
