I am sure the problem is with the code though. I would expect the following C# code to work, but I am not getting any response back (low to high) from the camera I am trying to interact with. I am using a NULL modem cable with the TX/RX and all the handshake pins swapped (verified). The documentation for interacting with the device is described here. I am trying to communicate with a device using C#/.NET's SerialPort class.
