We present axion-dilaton black-hole and multi-black-hole solutions of the low-energy string effective action. Under SL(2,[ital R]) electric-magnetic duality rotations only the hair'' (charges and asymptotic values of the fields) of our solutions is transformed. The functional form of the solutions is duality invariant. Axion-dilaton black holes with zero entropy and zero area of the horizon form a family of stable particlelike objects, which we call [ital holons]. We study the quantization of the charges of these objects and its compatibility with duality symmetry. In general the spectrum of black-hole solutions with quantized charges is not invariant under SL(2,[ital R]) but only under SL(2,[ital Z]) or one of its subgroups [Gamma][sub [ital l]]. Because of their transformation properties, the asymptotic value of the axion-dilaton field of a black hole may be associated with the modular parameter [tau] of some complex torus and the integer numbers ([ital n],[ital m]) that label its quantized electric and magnetic charges may be associated with winding numbers.
