Maybe 5dpo can be enhanced to meet this requirement. Maybe this is
easier than porting parts of AsyncPro.
I did only take a very small look at 5dpo. It might be done to provide
an internally multi-threaded unit that features a main-thread-event
interface. This is by far the most challenging issue, as it needs an
implementation of a fast thread-safe FIFO for the serial (receive) data
and a portable implementation for firing asynchronous queued main thread
events from threads.
Calling synchronous events right within the (receive) thread for
"advanced" server-type applications is a nice to have and easy to do add-on.
