Hello, Sure. I'm willing to hear more about your changes and patches! To reproduce problems I've seen, try to download Peter Wemm's stress suite, compile it, and run PTY code. As I recall, after unpacking stress2.tgz you'll have run.sh script and pty<some_extension>. You run it by typing: ./run ./pty<some_extension_maybe_conf>. Try to switch to other virtual terminal and login. For debugging stuff, where I liked to put printf()s and KASSERTs here and there, I used window(1), because it doesn't bomp you with tons of function calls, and creates (AFAICT) 2 vTTYs. Let me know if you find something, -- Wojciech A. Koszek wkoszek@FreeBSD.org http://FreeBSD.czest.pl/dunstan/
