Instantaneous start of USART transmission wanted

Hi everyone,

I have an application where I have to start transmission of a single byte from a USART within a small time frame after a hardware signal. Unfortunely a simple start by writing to the USARTs DR-register starts transmission with a 'random' delay of up to 1 bit time (probably due to the current content of the prescaler).
Is there a way to get rid of that start-of-transmission-jitter ?

Best regards,
