You could have posted your question there.  The more people are
posting the same question, the more likely it is that some of those
who can do something for it will notice it.

Sure, sending a mail to bugs@freebsd.org might have got you the same
in a simpler way.  But we _do_ follow Usenet, as the time permits.
(I've got a day job as well, even though i'm right now posting from
there.)

Sure, but you've been asking for the emulation.  Nobody has setup a
Linux cross-compilation environment under FreeBSD anyway, so the
missing termio.h is a moot point.

All recent SysV's do have termios as well.  Only SVR3.2's didn't, but
they are a very aged technology these days.

Again, if you care to contribute a termio emulation layer for FreeBSD,
we don't mind including it into libcompat.  Nobody has been pressed to
do this yet.
