I'd like to know if there is a recommended way to send a BREAK condition on UART0 or UART1 in the ATmega128. Some UARTS on other processors implement this as a bit in one of the UART control registers.
My initial thought is to disable the transmitter, pull the TxD pin low for the required time, take it high again and re-enable the transmitter.
There may or may not be other ways; that is why I'm asking.
