    It may happen if your transmitter use SEROUT/SEROUT2/DEBUG and the pin idle state is not set before sending the first data.

    Post your both code, receiver and transmitter end.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    I use a VB program not a pic as the transmitter. I can leave the program running while the pic is powered down. I give the pic a few seconds stabilization time after power up before the next transmission is sent

    Ok then, modify your VB program to send few garbage character, then a Synch String (let's say OK), and in your ISR use WAIT("OK") . See if this solve your problem.

    I'm sure this would work, I just figured I would see if anyone knew why I can't get it to work as expected. It isn't critical to the application, just one of those annoyances I figured most people weren't living with
