try:

port.RtsEnable = true;
Thread.Sleep(1000); // ~1000 ms pulse width 
port.RtsEnable = false;

Be aware that the behavior of the RTS pin can be unexpected before opening the port (from my experience it's depending on your hardware, FTDI chips goes on/off several times on initializing).

Suggesting to use some real RS232 relay (which is very cheap) - for full and stable control over the voltage and the state.
