Loopback test for Serial ports

Does anyone have, or know where I can find schematic/pinout + software source code (any language) to go with it for the Loopback test for the serial ports?

As I understand it, there are severtal ways to do loopback plug for serial port test, and therefore software must be specific. I founf a lot of pinouts for lopback plugs for various existing commercial diagnostics software tools, but I couldn't find any free software that do these tests. And I was sure I saw qbasic source years ago, but now when I need it I can't find anything
