As far as I know CTS/RTS and DCD/DTR are hardware handshaking signals but controlled by means of software. If you configure the serial port not to use hardware handshaking the signals are ignored and can be used for something else. You could try it, disconnect the bridges that you made on the RS232 connector and link it to your spy-circuit. Use Hyperterminal, switch of handshaking (hard and software) and see if data comes through, it should work. I say Hyperterminal because I have no idea how your MTTTY code is handling handshaking, in Hyperterminal you can switch it off, or any other terminal software that has this option of course.
