In this paper, an open fermionic string propagating freely and one moving in a constant antisymmetric background field are discussed. In contrast to several discussions in which boundary conditions are taken as primary Dirac constraints, we get the anti-Poisson brackets among the Fourier modes first. Then the anti-Poisson brackets among the string's coordinates can be obtained. It is shown that due to nontrivial boundary conditions, the string's end points are antinoncommutative. Contrary to the previous approaches in which the antinoncommutativity is obtained as the algebraic result, we find that antinoncommutativity originates dynamically.
