Look at the source code for the pty driver: xnu bsd/kern/tty_pty.c The ttioctl() called there is implemented in: xnu bsd/kern/tty.c -- Terry _______________________________________________ Do not post admin requests to the list.

I strongly recommend utilizing it to implement the tty line discipline, rather than trying to "roll your won", since you are unlikely to get things like controlling tty's correct on your own. PS: TIOCGETA_64 indicates that your test program is a 64 bit rather than a 32 bit program; you will likely want to use a 32 bit test program, since I can't guarantee all aspects of the tty driver have been made 64-bit happy in whatever version of the OS you're running.
