Not quite true.  if you assume ttydN corresponds to cuaN, then setting
'ttysoftcar' on ttydN is the same as setting it on cuaN.  (Try it, set
it to -n on one, then -y on the other, it will be -y on both.)   Although
you can't use 'ttysoftcar' on ttydN, you CAN use it on cuaN, which
accomplishes the same thing.
