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:

arduino-tvout/pollserial/pollserial.cpp

Lines 119 to 122 in 74e6853

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

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!
