PEEK function on UART serial buffer

Hi is it possible in FC8 to PEEK (look at without removing) the first byte on a UART buffer? This woud be really helpful in synchronising actions a serial data stream.
Regards,
Chris

Hi Chris,
I'm afraid on the hardware if you read the buffer then the value is removed. A circular buffer combined with a UART RX Interrupt would allow you to read the data as and when you're ready and allow you to peek at the data.
