I am trying to splice 4 wires out of the RS232 serial cable (the 9-pin type) and wire them to a circuit board. The 4 wires would control 4 signals: DataIn, DataOut, SerialClock, and ChipSelect. The serial clock would synchronize the DataIn and the ChipSelect is asynchronous. DataOut must coincide with SerialClock also; therefore there are 3 signals that must be able to switch concurrently. All the handshaking enabled by RS232 is thus unnecessary in my opinion. Does anyone know of how this can be done?
