        Any mis-configured serial port settings (baud, parity, data
        bits, stop bits) can cause this behaviour.

        In /general/, the hyperterminal default settings of 8/N/1 
        should work in most, but not all cases; some older mainframe
        based equipment, for instance, will use 7 data bits with Even
        parity.  If memory serves, in the past I have also had to
        use even more esoteric settings for parity, such as mark
        or space, but that was 2 decades ago.
