  Based on the notion of thin sets introduced recently by T.~Banakh,
Sz.~G\l{}\k{a}b, E.~Jab\l{}o\'nska and J.~Swaczyna we deliver a study of the
infinite single-message transmission protocols. Such protocols are associated
with a set of admissible messages (i.e. subsets of the Cantor cube
$\mathbb{Z}_2^\omega$).
  Using Banach-Mazur games we prove that all protocols detecting errors are
Baire spaces and generic (in particular maximal) ones are not neither Borel nor
meager.
  We also show that the Cantor cube can be decomposed to two thin sets which
can be considered as the infinite counterpart of the parity bit. This result is
related to so-called xor-sets defined by D.~Niwi\'nski and E.~Kopczy\'nski in
2014.
