Does this driver correctly support cua(4) device nodes?
If it doesn't, then my position would be "no, that is a minimum required
featureset". And 'd' dialout support isn't the same, it must be cua.
(Quirky different behaviours between tty devices are super annoying and
end up as complaints on the mailing list, so a tty driver MUST support
cua(4) correctly).
A quick review of the driver indicates: No cua support.
Frankly, it's the kind of driver that needs the work, or a visit to the Attic...
Want to try fixing it? It is not trivial..
