  We discuss the implications of assuming a four-zero Yukawa texture for the
properties of the charged Higgs boson within the context of the general 2-Higgs
Doublet Model of Type III. We present the charged Higgs boson couplings with
heavy quarks and the resulting pattern for its decays, including the decay $H^+
\to W^+ \gamma$ at 1-loop level. The parameters chosen can still avoid the $B
\to X_s \gamma$ constraint, the perturbativity and $\rho_0$ bound. Also, we
present the constraints of $ B0-\bar{B}0$ mixing and of the radiative
corrections to the $Z b \bar{b}$ vertex in the regime small $ \tan \beta$. The
production of charged Higgs bosons is also sensitive to the modifications of
its couplings, so that we also evaluate the resulting effects on `direct'
$c\bar{b}\to H^++c. c.$ and `indirect' $q\bar q,gg\to \bar t b H^++c. c.$
production. Significant scope exists at the Large Hadron Collider for several
$H^\pm$ production and decay channels combined to enable one to distinguish
between such a model and alternative 2-Higgs doublet scenarios.
