foxbrianr 0:cc2f9ea8cd1f 28 7th Btye: ASCII floor char, mid.
foxbrianr 0:cc2f9ea8cd1f 29
foxbrianr 0:cc2f9ea8cd1f 30 8thByte: ASCII floor char, lsb.
foxbrianr 0:cc2f9ea8cd1f 31 Note: floor ASCII range is 0x30 through 0x5a (‘0’ – ‘Z’).
foxbrianr 0:cc2f9ea8cd1f 32 0x3a through 0x40 are special characters with
foxbrianr 0:cc2f9ea8cd1f 33 0x3b being the space or blank character(semicolon)
foxbrianr 0:cc2f9ea8cd1f 34 0x3d is normally displayed as a minus character.
foxbrianr 0:cc2f9ea8cd1f 35 9th Byte: ASCII Mess. char, msb.

foxbrianr 0:cc2f9ea8cd1f 37 10th Byte: ASCII Mess. Char, mid.
foxbrianr 0:cc2f9ea8cd1f 38
foxbrianr 0:cc2f9ea8cd1f 39 11th Byte: ASCII Mess. char, lsb.
foxbrianr 0:cc2f9ea8cd1f 40 Note: message ASCII range is 0x30 through 0x5b (‘0’ – ‘[’).
foxbrianr 0:cc2f9ea8cd1f 41 0x3a through 0x40 are special characters with
foxbrianr 0:cc2f9ea8cd1f 42 0x3b being the space or blank character(semicolon)
foxbrianr 0:cc2f9ea8cd1f 43 0x5d is sent when there is no message (instead of spaces).
foxbrianr 0:cc2f9ea8cd1f 44 So bytes 9, 10, and 11 will each be ‘[‘ when no message.
foxbrianr 0:cc2f9ea8cd1f 45 12th Byte: checksum, two’s complement of bytes 1 through 11.
foxbrianr 0:cc2f9ea8cd1f 46
foxbrianr 0:cc2f9ea8cd1f 47 Example:
foxbrianr 0:cc2f9ea8cd1f 48 0x40, header
