Hello List, As I understand the datasheet, the 18F4550 contains a 2 byte RX buffer for the EUSART. If there a way to clear this buffer without reading off the data ? I've looked at the RCSTA register and was hoping to see a ClearBuffer type bit but nothing. Many thanks, Joe -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
