Curses setting tty mode through stderr???

Hey SCO, is the initscr() function in curses (termcap version) setting
the terminal input mode to RAW through stderr??

I am using curses to write to devices other than 'stdout'.  I do this
by opening the other device and then dup2'ing stdout and stdin to its file
descriptor before calling initscr().  I start the task in the background
so that the original terminal is freed for other stuff.  I want to leave
stderr pointing to the original terminal for various error messages.

It worked great in the 2.2.2 development system of Xenix 386, but now
after I start the program, the original terminal is left in RAW mode,
requiring me to 'stty sane^J' -- somewhat of an annoyance.  (The other
solution is to call crmode(), echo(), and nl(), after initscr().)

When I redirect stderr to an unused multi-screen on the command line
thusly:
		$ testprog 2>>/dev/tty09 &

the problem doesn't occur, leading me to believe that initscr() is using
stderr.

What gives (and why)?
