 * (What sort of trouble?  Well, to pick some examples from SunOS, since
 * that's the system I know best at present, using TIOCSTI to push back
 * the literal-next character simply does not work (it somehow
 * literal-nexts itself), and the dsusp character doesn't perform the
 * delayed-suspend action - it appears to do nothing, as if the dsusp
 * character were nothing but a place to stash a random character for
 * rlogin.)

In fact, if you read the man page for tty(4)/termios(4) you will find
that dsusp is completely ignored in SunOS 4 due to the fact that the
tty driver and supporting routines have been completely rewritten.
The only place that dsusp is recognized is, as you have pointed out,
rlogin, and they do disclaim this somewhere in their documentation.

System V was a mistake.
