You may be seeing an 'escape' char that preceeds a 0x7d (I think
that's the value that's escaped). See this for details:

Hi, All:
Can anyone help me with the the xbow MTS400 problem. When I
receive the packet, the packet length is changing, sometimes is 40 bytes
and sometimes is 39 bytes. I found a dump(0xd5) byte is inserted in to
message? Can anyone tell me how to make the packet to be accordance, not
changing the length? Thank you.
