Reading from pollserial returns invalid data every 65th byte

[rjhelms]

Pollserial is returning invalid data every 65th byte. It seems like the logic is not wrapping the tail around correctly when the end of the buffer is reached:

This should likely increment the tail and then wrap if needed, something like:

if (rxbuffer.tail == BUFFER_SIZE)
    rxbuffer.tail = 0;
else
    rxbuffer.tail++;

Hi!

This is my solution:

        if (rxbuffer.tail == BUFFER_SIZE-1)
            rxbuffer.tail = 0;
        else
            rxbuffer.tail++;
        return c;

Best regards!
