Abbreviated ASCII
This message format is designed to make entering and viewing commands and logs simple. The data is represented as simple ASCII characters, separated by spaces or commas and arranged in an easy to understand format. There is no 32-bit CRC for error detection because it is meant for viewing by the user.
The Abbreviated ASCII message header structure is described in Table: Abbreviated ASCII Message Header Structure.
