+ *
+ * * 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.
