Arduino for STM32

When setting `Serial_begin_config(19200, SERIAL_8N1);` everything works ok but in my project i need `Serial_begin_config(19200, SERIAL_8E1);` configuration and it doesn't work like it should. It doesn't mirror `Serial.begin(19200, SERIAL_8E1);` arduino Uno functionality

Hi,
don't know if E1 is really supported. Could you open a ticket on GitHub to track this. And also add some more description, ex board used, IDE version, small sketch example... all relevant information which help to support you.
