Using the CLEO-c detector at the Cornell Electron Storage Ring, we have measured inclusive and exclusive cross sections for the production of $D^+$, $D^0$ and $D_s^+$ mesons in $e^{ +}e^{ -}$ annihilations at thirteen center-of-mass energies between 3.97 and 4.26 GeV. Exclusive cross sections are presented for final states consisting of two charmed mesons ($D\bar{ D}$, $D^{ *}\bar{ D}$, $D^{ *}\bar{ D}^{ *}$, $D_s^+ D_s^-$, $D_s^{ *+} D_s^-$, and $D_s^{ *+} D_s^{ *-}$) and for processes in which the charmed meson pair is accompanied by a pion.
