If you want to use the parallel port and MOSFETs, search for inpout32.dll. it is for Windows to interface with Basic or some varieties of "C".
Otherwise, X10 is a protocol for communication among electronic devices used for home automation (domotics). It primarily uses power line wiring for signaling and control, where the signals involve brief radio frequency bursts representing digital information. A wireless radio based protocol transport is also defined. https://en.wikipedia.org/wiki/X10_(industry_standard)
