The original reason for the bifurcation in the first place had to do with
locking difficulties and getty (if I'm not mistaken) and have since been
fixed. As a result, cua devices are being discouraged in favor of ttyS
devices for both dial out and dial in. As a seperate data point. I still
use the cua device on my dialout modem, with ppp, and have no problem.
It's not that they are non-functional, it's really a "conformity" issue,
as best I can tell.
To shorten the answer: use ttyS for both dial in and dial out.
