    We have a number of Benq 660DX projectors and are
    struggling to control them via an RS232 serial connection.
    We initially struggled to get any response from the
    projectors until realizing that the Benq-provided diagram of
    the cable pin-outs was reversed. Now we are getting
    some response. Unfortunately, we have two differing sets
    of protocol documentation from Benq, neither of which
    seems to be correct. We'd greatly appreciate hearing from
    anyone who has managed to "talk" to their Benq
    projector!

    Cheers,
    darran.
