Looks like it is hardcoded, I just tried a different one and it fails.

At least I can now continue playing with it... eventually I'll release
my code once it reached a halfway usable state. Currently I still
struggle a little with the protocol implementation which would need a
state machine and I am still reluctant to implement one and wait for
another inspiration instead ;) But it seems it is not coming...
