  We study the perspectives of resonant and nonresonant charmed meson
production in $\bar{p} + A$ reactions within the Multiple Scattering Monte
Carlo (MSMC) approach. We calculate the production of the resonances
$\Psi(3770), \Psi(4040)$ and $\Psi(4160)$ on various nuclei, their propagation
and decay to $D, \bar{D}, D^*, \bar{D}^*, D_s, \bar{D}_s$ in the medium and
vacuum, respectively. The modifications of the open charm vector mesons in the
nuclear medium are found to be rather moderate or even small such that dilepton
spectroscopy will require an invariant mass resolution of a few MeV.
Furthermore, the elastic and inelastic interactions of the open charm mesons in
the medium are taken into account, which can be related to $(u,d)$-, $s$- or
$c$-quark exchange with nucleons. It is found that by studying the $D/\bar{D}$
ratio for low momenta in the laboratory ($\leq 2-2.2$ GeV/c) as a function of
target mass $A$ stringent constraints on the $c$-quark exchange cross section
can be obtained. On the other hand, the ratios
  $D^-_s/D^+_s$ as well as $D/D^-_s$ and $D/D^+_s$ at low momenta as a function
of $A$ will permit to fix independently the strength of the $s$-quark exchange
reaction in $D^-_s N$ scattering.
