No, we just addressed a point brought up by your message, namely that
your suggestion didn't work on all flavors of UNIX.

The only kernel implementation I know of offhand that doesn't overload
them is the 4.4BSD one (I'm not certain, but I think it doesn't overload
them).  S5Rn for the 386, and SunOS for the 386i, overload them.

For better or worse, some systems take numeric values for the "min" and
"time" arguments to "stty", and others take character arguments; unless
there's some form they all take, using "stty" to set "min" and "time"
therefore also depends on your UNIX implementation.
