The voltage when hooking the ground to pin 5 (GND) and the lead to pin 3 (TX) is -06.41V. I measured the frequency of the pin as well and when I use putty to hookup to the serial port I can see the frequency jump around when I press keys, so it seems like everything is hooked up properly.
I used this as my diagram: Tech Stuff - RS232 Cables and Wiring
So if my voltage is 6+, what am I missing?
