Isn't this more confusing now?  I don't have access to the BACnet standard, but surely it's either big or little endian 
and not some mix of both?  Assuming the reporter of bug 5769 is correct and the Info column displays the values of the 
low and high limits correctly, then the protocol is ENC_BIG_ENDIAN.  All of the fields affected by r38106 are either 
FT_UINT8's or FT_BOOLEAN's spanning 1 byte, so endian-ness really doesn't matter, but if someone does the old 
"copy-and-paste" thing later on, [s]he might incorrectly copy an ENC_LITTLE_ENDIAN when it should be ENC_BIG_ENDIAN.
