45  To have alt_printf output to uart:
46  1. Add -DPRINTF_UART to your compile flags
47  2. Add alt_p2uart.c and alt_printf to your project
48  3. (optional) set -DDEFAULT_TERM=term0 or -DDEFAULT_TERM=term1 to specify which UART to use
49  4. (optional) If you with to initialize the uart yourself (for instance, if you want to read from the uart),
50  a. Initialize UART0/1 (Make sure it matches step 3 above)
51  b. Use term0_info->mUart or term1_info->mUart for the handle in part a.
52  c. Set term0_info->init_done=1 or term1_info->init_done=1
53  d. See alt_p2uart.c:init_uart as an example
