Similarly, they would not care about sync vs. async.
PLATO used Bell
202 modems for 1260 bps 21 bit sync one way, slow speed (50-100 bps?)
10 bit plus parity async the other way, on a standard 2 wire phone
link.
When did using async parity go out of style? It seems to have slowly
been disappeared from the scene, but I think that some MCUs with
serial-interface bootloaders (e.g. STM32) still require parity of one
sort or another (could be mark or space).
This goes back to the question about not having any additional
information to determine async bit rate.
