Generate the Tx service request after the symbol is shifted out of the UART. This is useful when the UART is connected to an RS485 transducer which has a separate transmit enable gpio/line. Hence it's important to know when the transmission actually finishes so that the drive enable line can be disabled. Signed-off-by: Andriy Gelman <[email protected]>
