    Just remember - when using the UART, your program writes the output buffer and moves on, which means that you can still be outputting a byte many instructions after the HSEROUT. You should wait at least two byte-times after any HSEROUT command before you change the baud rate.
    Hi Charles,
    Happy Thanksgiving to you and all who share this forum!
    I am thankful to all who post here.

    So are you saying, the statement posted below:
    <h4>DEFINE HSER_SPBRG 32 ' __ _ FOR 20MHZ 129 = 2400, 32=9600,25 @ 4 for 2400, </h4> might be written as something like:<h4> IF PortB.n = 1
    THEN HSER_SPBRG = 32
    ELSE
    HSER_SPBRG = 129</h4>
    JS

    EDIT
    AHHHH SOOO
    I see, just define it to your default and change it later with SPBRG = "new setting number"
    <h3>THANKS CHARLES !</h3>
