In order to transmit data, the driver enables Tx and sleeps until *board_write is set to 1 by the interrupt handler. It can happen, though, that the data is sent even before the process is asleep. In this case *board_write must be set to 1 anyway, otherwise we will be waiting for a condition that will never be true.
