We report results on the differential and total cross sections for inclusive production of the charmed particles D/sup *//sup +/, D/sup *//sup 0/, D/sup 0/, D/sup +/, D/sub s/, and ..lambda../sub c/ in e/sup +/e/sup -/ annihilations at ..sqrt..s = 10.55 GeV. Widely used quark fragmentation models are discussed and compared with the measured charmed-particle momentum distributions. This comparison, as well as that with measurements at other center-of-mass energies, shows the need to take QCD corrections into account and their importance for a correct interpretation of the model parameters. The observed rate of D/sup 0/ and D/sup +/ production is compared to the expected total charm production cross section. We measure the probability of a charmed meson being produced as a vector meson and the D/sup *//sup +/ decay branching fraction into D/sup 0/..pi../sup +/.0
