I added the -h option to my agetty call.  Now that I've explicitly
told the terminal's setup to use rts/cts, I feel pretty confident
that I should keep the -h option.  But nothing seems to change.

I get the feeling that when I modify the line in /etc/inittab, it
seems like things aren't being reset after I do a "telinit q".  I
say this because the terminal seems to react similarly no matter
what command-line options I give agetty (with the exception of
ttyS1).  The most frustrating thing, though, is that the reaction of
the terminal to my typing on it or doing something like "echo "test"
> /dev/ttyS1" is so non-repeatable.  I might press the 'a' key once
and it outputs an 'x'; the next time it may or may not output
anything.  And there's the same non-repeatability when everything
seemed to work briefly but then not work after I logged out.
