Abbreviated ASCII

This message format is designed to make the entering and viewing of commands and logs by

the user as simple as possible. The data is represented as simple ASCII characters separated by

spaces or commas and arranged in an easy to understand fashion. There is also no 32-bit CRC

for error detection because it is meant for viewing by the user.
