Hello Andrew, I can not see such an error with a FT232R! Your diagram is propably done by the Saleae Logic Logic analyzer. The analyzer missanalyses the the trace. If you space the character like with the patch below and if you don't overwrite the CFLAG setting PARENB with the call to cfmakeraw(&

[BUG] FTDI driver framing error with even parity

This is seen on widely used ftdi ft232rl chips. Setting the parity to something like 'even' results in occasional framing errors when transmitting data. Relevant timing diagrams from the logic analyzer are attached to this bug: https://bugzilla.kernel.org/show_bug.cgi?id=47921 -- Regards, Andr
