/*

        serial.h - Contains definitions and function prototypes for the RS232 serial port

  author(s): pkv

  Directions:

  Call the initialization function for the serial port you wish to use.  Then, use

  either the provided functions or the stdio functions (fprintf, etc) to read and

  write characters to the serial ports.

  UART Mapping:

    usb_*() -> UART0

    xbee_*() -> UART1

  Options: (Add the following defines to your code to configure this library)

    #define USB_BAUD { 115200 | 9600 } <= pick ONE value from in here

    #define XBEE_BAUD { 115200 | 9600 } <= pick ONE value from in here

    #define USE_STDIO

  Note: If you enable USE_STDIO, the first init function that is called will 

  automatically be linked to stdin, stdout, and stderr.  To use the baud rate 

  commands, add something like the following to your code:

  #define FOO_BAUD 9600

  **UNLESS YOU KNOW WHAT YOU ARE DOING, PLEASE DO NOT CHANGE THIS FILE**

  Many, many other people use this file in their code.  If you change it, you will

  probably break all of their nice code.  You should not need to change anything in

  here, except to accomodate new hardware.
