Hmm, this sets bit 6 in UCONn to generate an error interrupt upon an
exception, but there is no handler for error interrupts
However, table 11-1 (Interrupts in Connection with FIFO) says about Error
Interrupts in FIFO Mode:

So maybe an overrun error means that the fifo is full and not that we
lost a byte?
