I may be thinking of TIOCREMOTE (from the solaris man page: "In normal
usage, a write of data is like the data typed as a line on the terminal;
a write of 0 bytes is like typing an EOF character"), but unfortunately
on linux the tty_ioctl man page says:  "The BSD ioctls TIOCSTOP,
TIOCSTART, TIOCUCNTL, TIOCREMOTE have not been implemented under Linux."

Still I'd think there would be some sort of equivalent functionality...
