Query: $e^+e^-\to H^+H^-$ signals at LEP2 energies in the Minimal
  Supersymmetric Standard Model   In this paper we compare $H^+H^-$ and $W^+W^-$ into four-fermion production
at centre-of-mass energies typical of LEP2 and somewhat larger. The theoretical
framework considered is the Minimal Supersymmetric Standard Model. The interest
in exploiting the $e^+e^-$ CERN collider at values of $\sqrt s$ greater than
192 GeV could come from the discovery of Supersymmetric signals during runs at
lower energy. If these indicate that a charged Higgs boson exists in the mass
range $\MH\approx95-105$ GeV, then a few years of running at $\sqrt s=205-215$
GeV and nominal luminosity could make the detection of such scalars feasible,
in the purely leptonic channel $\tau\nu_\tau\tau\nu_\tau$ and, for small
$\tb$'s, also in the semi-hadronic(leptonic) one ${jj}\tau\nu_\tau$. Charged
Higgs bosons of the above nature cannot be produced by the beam energies
approved at present for LEP2. However, if runs beyond the so-called `192 GeV
cryogenic limit' will be approved by the CERN Council, our selection procedure
will enable us to establish the presence, or otherwise, of charged Higgs bosons
in the mentioned mass range
