 Mod5213 I2C2Serial
 This program will illustrate how to use the NetBurner I2C driver to transmit
 multi-master or master-only I2C.  This application should be used with multiple
 NetBurner modules and at most 1 if any configured to be master-only. 

 Please note that jumpers 11 and 12 should be put on the MOD5213 developement 
 board to enable the I2C pull up resistors.
