    The origin of millisecond pulsars still remain mysterious. Direct
    proof of the standard spin-up by accretion hypothesis,the detection
    of pulsations from LMXBs,is still eluding us.The soft Xray transients
    (e.g. Cen X-4) are supposed to be LMXBs in their last phase of evolut
    ion and are expected to contain spun-up millisecond pulsars.If so,dur
    ing quiescence the millisecond pulsar should be able to ward off accr
    etion, offering us an opportunity to directly see the millisecond pul
    sations. A study of the X-ray spectrum, the X-ray flux (proportional
    to mass transfer rate), radio & X-ray pulsar searches & optical obser
    vations offer us the most direct constraint on the properties of the
    putative millisecond pulsar. ASCA time is being requested as a part
   of a multi-wavelength effort.
