Please check my understanding of serial i/o:
If I look at the voltage at the TX pin when the pic sends a byte via its
usart, I should see a high going low for the start bit, then a bunch of ups
and downs, then it should go high for the stop bit and stay that way.  Do I
have that right?

Between the start and stop bits, does high mean 0 or 1?

Is there some bit in the pic that inverts the levels?
