If you switch off 'hardware handshaking' in the communications software (Hyperterminal is horrible, I recommend and use TeraTerm), you won't need any of the handshaking lines to be connected.

I routinely use the PAPERCLIP method for testing serial ports, though the paperclip can be readily subsituted for a screwdriver blade, pair of tweezers, or more or less anything else lying around on the bench...
