    The problem with sayzer's circuit is that it will not work for max232epe chips , they will get hot real hot

    the switching caps need to be ten times smaller 0.1uF

    Using ST232 and MAX232, I use 1uf elect type for many years now. Never had a heat problem.
    For 232epe, some additional care may be required as Richard mentioned.
