Jacques,
Another option, if you have some influence over the the sending system, is to switch from encapsulation to length encoding. Then the individual bytes won’t matter.
Your transmission would go from:
<0b>hello <0b>world<0d>
To:
<00><00><00><10>hello <0b>world
(This is 4 byte, binary, length encoding. There are a total of 16 characters in the transmission including the length field, the <10> in hex is ascii 16)
In Cloverleaf, this would be a configuration change and not a PDL.
cheers,
