The UART emulator is needed in applications that require more UARTs than the ones provided by STM32F4 microcontrollers.
The STSW-STM32156 firmware provides an emulated full-duplex UART which supports up to 9 data bits and up to115200 baud rates.
The STSW-STM32156 firmware also offers an example of communications between a hardware and a software UART.
For more details refer to application note AN4457.
