Allen H. Porter The exact pinout of the cable depends on the device sending or receiving. But in most cases it will be some version of TRS (tip, ring, sleeve) to TRS or TRS to DB9. And it is usually tip to pin 2(transmit data), ring to pin 3(receive data), and sleeve to pin 5(ground). Or tip to pin 3, ring to pin 2, and sleeve to pin 5.
