Serial ports. Oh the pain, the pain.

I have a whole box of serial cables that I have accumulated over 20 years of use. I have male-female, female-female, and male-male straight-through cables, and a null modem cable. This lets me make up whatever is called for. I verify my connection using one or two of these cables, then build a custom cable. If the custom cable doesn't work, I know it's the cable.

You can connect a serial port using only transmit, receive, and ground, but even at 9600 baud, a steady stream of bytes is likely to overrun your PC's receiver buffer. That's why you want to connect RTS and CTS, which do hardware handshaking. You can do software handshaking using XON and XOFF if your USB-serial box understands that and your terminal software understands that.
