Hello Guy,

        6 or 7 - escape
        7 or 6 - DLM Bootloader

The information you quoted said "111=escape, and 111=DLM Bootloader"; I assume one of those 111's is supposed to be 
110.  Which one of them should be 110?

6 - unused
7 - escape and DLM Bootloader (unfortunately).

The DLM Bootloader packet from LMCI USB dongle looks like this:

+-------------------------+
|        Dongle Code      |
|        (1 Octet)        |
+-------------------------+

|        (2 Octets)       |

|        Preamble 2       |
|        (1 Octet)        |
+-------------------------+

.                         .
.                         .
|       (0-32 Octets)     |
+-------------------------+
|      LRC Checksum       |
|       (1 Octet)         |
+-------------------------+

Best Regards,
