Hello Uwe, The break condition is issued when the signal is held low longer than die total frame length. The Frame error on the other side indicates that e.g. the parity bit is invalid. The break state is often used in old protocols to act as a 257th character mostly as begin-of-frame or out of band data indicator.

I looked at the STM32 reference manual, and someting like "BREAKERROR" is not mentioned there. Probably a line kept low for longer than one frame should produce a BREAKERROR? Where does it differ from a framing error?
