* to use task driven serial I/O to ti386 BSPs. This patch leaves thex
* default I/O mode to be IRQ. If you want to use task I/O mode,
* then the tty_drv.c file needs to be modified. Basically, all
* you need to change is the data values of the termios callbacks
* structure. This callback structure is used in the tty1_open
* and tty2_open functions. The values you need to set are commented
* out in the source code.
