A remeasurement of the resonance near E_cm = 3.77 GeV in the e⁺e^- annihilation is presented. The properties of the resonance are used to deduce branching fractions of charmed mesons into hadronic final states. Several previously unseen decay modes are reported. Decays into Cabibbo suppressed final states are observed. The inclusive properties of D meson decays are studied, including strangeness and charged particle multiplicity. The semileptonic branching fractions for D^o and D^∓ are measured, providing a determination of the relative lifetimes of these particles.
