patmcna 4:0e2980186bed 16 6/14/2016 - Everything is working! 115200 baud with array sizes of 32 bytes seems to be
patmcna 4:0e2980186bed 17 what is working reliably.
patmcna 4:0e2980186bed 18 - Keeping array sizes at 32 seems easy to send and receive over serial. Trying
patmcna 4:0e2980186bed 19 to figure out why serial receive hangs with more than 32 bytes of data

patmcna 4:0e2980186bed 21
patmcna 4:0e2980186bed 22 6/1/2016 - test to see if the recieve interrupt is handling the serial transfer and the
patmcna 4:0e2980186bed 23 read_line() does not need to be called
patmcna 4:0e2980186bed 24 - set up receive buffer to be stored into an array
patmcna 4:0e2980186bed 25 ... this will depend on where serial data is being received
