Maybe Ed can give you the > function name you need to call to do that? Yes. You need cfmakeraw() to do that (or do everything yourself). See src/lib/libc/gen/termios.c to see what it does. So what I'm interested in, is the following: "even that device is answering requests slower and slower until it stalls completely within 1 hour" Could you run `pstat -t' to see what's going on when it stalls? This nifty tool just gives some random statistics on TTYs. Very useful to see what's going on. Where data is stuck, etc. etc. -- Ed Schouten <ed@80386.nl> WWW: http://80386.nl/ [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (FreeBSD) iEYEARECAAYFAkq32M0ACgkQ52SDGA2eCwUbJQCbBC0jZTf2LS9jbO5ITvDqR4ds m5sAn0HJnlFnL4YJNpGtzTjlvXAjAI4/ =2P0a -----END PGP SIGNATURE-----
