264 * mode, in one shot, and exits.
265 *

275 * -writes-data-to-uart
276 * -enable-tx-intr
277 *
278 * Once data bits are pushed out, controller raises the Tx-room-avail-Interrupt.
279 * The first thing Tx ISR does is disable further Tx interrupts (as this could
280 * be the last char to send, before settling down into the quiet polled mode).
281 * It then calls the exact routine used by tty layer write to send out any
282 * more char in tty buffer. In case of sending, it re-enables Tx-intr. In case
283 * of no data, it remains disabled.
