Since sq1plus is not a cygwin program, it doesn't fully understand cygwin
tty's.  So, it doesn't realize that it should be turning off echoing since
cygwin tty's are just represented as pipes to non-cygwin aware programs.

I doubt that there is anything you can do to rectify this behavior other
than to make some kind of wrapper for sq1plus which redirects stdin/stdout
to the console and then calls sq1plus.

Maybe something like:

sq1plus < /dev/console >/dev/console 2>&1

might work, but no guarantees.
