* comm/tty_drv.c, comm/uart.c, comm/uart.h: Adds the capability
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.
