As quoted from <549@ubu.warwick.UUCP> by ham@warwick.UUCP (Hot Air Machine Project):
+---------------
| ....And the bugfix.  stty.c performs its ioctl()s on file descriptor 0 (stdin)
| this means that to change the settings on terminals other than the one you
| are using, you have to type e.g: stty -echo < /dev/tty1
| which is rather counter-intuitive, not to mention different to UNIX.  The
| solution is to replace all occurences of "ioctl(0," by "ioctl(1," in stty.c --
| I think there are four of them.
+---------------

V7 stty did do it this way, doing ioctls to fd 0 and printing output to fd 1.
Later versions moved ioctls to fd 1 and printed output on fd 2.  (I'm using a
truly ancient Unisoft 68000 V7 on an abandoned Pixel right now; if I knew how
to program in TMS9900 machine language I might try to bring up Minix on this
beast.  (All I/O including console I/O goes through the TMS9900.)
