In the program, internal temperature and voltage measurements are taken in

the CR1000 and sent out in an ASCII message header. We haven’t covered the

GTX command structure/format and so this program will simply allow the GTX to

go into sleep mode, and then wake it up with carriage returns until we get the

‘>’ character returned from the GTX signifying that it is awake and ready for

communication. Later, we will format the data into the actual GTX format for a

random or timed message.
