I see what you mean. Not much info indeed. But it’s telling exactly what Serial.Flush actually does.
If you Click on the ‘Serial’ lemma from your link it will bring you back to the main ‘Serial’ info, and if you click from there on ‘Flush’ it will show Writeable.Flush: that’s the info I initially got.
In other words: the link from Serial’s main lemma to .Flush points to Writeable.Flush, and it’s info is wrong.

You’re right, very good info. I struggle with Serial Communication over 40 years now, and remembering my early years I know that sometimes data can be held up in the input buffer. That’s why I implemented this .Flush command, thinking it worked as a Writeable.Flush according the documentation. It took some time before I found out why sometimes commands waiting in the input buffer vanished…
