"In a DOS console, screen works, but in order to be able to reattach
detached sessions, you must set "tty" in the CYGWIN environment
variable.... If you use screen in a DOS console without CYGWIN=tty, you
will be able to detach sessions, but reattaching to them later is likely to
fail. Then you'll have to use 'screen -wipe' to clear out your old
unusable sessions, and you may have to manually kill their child
So it seems that screen users who are still using a DOS console need
CYGWIN=tty. I have no idea how many such people there are.
If CYGWIN=tty is going away, then we could simply tell screen users that
the DOS console is no longer supported in screen, since reattaching there
is likely to fail.
