00004 *This module handles all serial communications with a PC over USB. 
00005 *Serial code is attached to its own thread and is run when the RX interrupt is triggered.
00006 *The RX interrupt is triggered when someone starts typing in a PC terminal. 
00007 *The Scanf function is then started to capture the input. 
00008 *There are a list of commands that are used with serial:
00009 
00010 * readall
00011 * deleteall
00012 * read <n>
00013 * delete <n>
00014 * setdate <dd><mm><yyyy>
00015 * settime <hh><mm><ss>
00016 * sett <T>
00017 * state <x>
00018 * logging <x>
