not sure of this one, to be checked

6 numbers (2 hexa digits each) separated by ':'
plus ending 0 makes 18 bytes, not 6, let's put 20

- LMSSDR was not handled
- bad #if usage
- bad indentation

still not very clean, but better

I removed this variable entirely because it's not used.

Maybe the bug is that it's not used after being set?
To be checked and fixed at some point.

this variable does not seem to be used, to be removed?
