    host can send delimiter text always if desired whether or not delimiter text is enabled. 9. All command characters are small letters (easier to differentiate from numbers, ie. s5 vs S5). 10. Commands are variable length. 11. Commands have CRC for error checking at the end of the command. The CRC is calculated from all the ascii characters, starting with the sync and ending with the comma before the CRC value.
