Actually, "as delivered", RxAsync lets you do it both ways!

If you don't have an open com port handle then use RxAsyncOpen
to get it.

If you already have an open com port handle then just pass it
it into the calls eg. RxAsyncRead etc, it'll be accepted, no
need to do the open, no problems, no questions asked, no quarter
given!

The only proviso with the 'direct' method is that the beast you
got the handle from better have opened it as READWRITE_DENYNONE!!!
(simplisticly speaking.)

 Cheers, Ian.
